The smallest all-rounder
The Microtector II G460 is the world‘s
smallest 7-gas detector with the following key features: With five sensor
positions, the G460 offers more than
previously possible in an instrument
of comparable size. The main innovation of the G460 is the continuous
and selective measurement of seven
gases simultaneously. Thus, it warns
of dangers of toxic, combustible gases
and vapours, but also oxygen deficiency and surplus. With a wide
range of sensors and accessories,
the G460 satisfies all applications
and requirements.
Performance tested for maximum safety
For confined space measurement,
where highly combustible gases/
vapours, toxic gases and oxygen
deficiency hazards may be present. It
is a legal requirement in EU countries
that gas detectors with functional
performance, tested and approved
to European standards must be used.
The G460 is certified to EN 60079-291 (combustible gas perfor-mance),
EN 50104 (oxygen) and EN 45544
(toxic).
In addition the performance test approval of the G460 includes methane,
propane, hexane and n-nonane so the
user is protected against the whole
range of combustible gases that may
be encountered. This means better
protection, and improved safety.
The G460 performance test approval
was issued by DEKRA and EXAM,
who are leading European notified
bodies, and independent experts
licensed to certify instrumentation
under the ATEX directive 94/9/EC
and also to conduct the perfor-mance
test approvals to EN standards that
are required by the ATEX directive.
Using performance tested gas detectors gives the user confidence that
the instrument will perform correctly
even under extreme conditions, and
in harsh applications and environments.

award for outstanding achievements
in design and functionality. In addition, users from all over Europe
voted for the G460 for its practical
and user-friendly features with
the GIT Security
Award in 2009.
Intuitive handling
A large graphic
display provides
clear readings of all data. With only
three soft-keys the G460 allows intuitive and user friendly handling
via a simple menu. Sensitive device
configurations and functions are protected against unauthorized access.

The large, easy-to-read graphic display can be rotated 180° by just
pushing a button – this allows the
display to be read easily even if the
detector is carried, or worn at the
belt. Pushing any button activates

the backlight for 10 seconds, before
it is deactivated automatically to save
energy. The zoom-function allows
easy reading of single measurement
values and shows additional information on the selected gas.
Award-winning design
The G460 is not only highly innova-
Smart sensor techno-logy
The G460 uses pre-calibrated, smart
plug-in sensors which can combined
in different combinations (see table).
All sensors have their critical information stored (i.e. gas type, detection range, alarm set-points, date of
calibration etc.) in a memory chip
attached to the sensor. This means
that sensors can be easily swapped
or replaced when required.
Typical characteristics of sensors used
in GfG instruments are long lifetime,
fast response, high measurement
accuracy and high specificity to the
target gas.
Patented CO2 and CH4 detection
The G460 can be equipped with our
new, patented, low-power multi-frequency NDIR sensor. This sensor can
detect up to four wavelengths simultaneously. This means that CO2 can
be detected in ranges from ppm to
%VOL, and combustible gases in the
%LEL and %VOL range if required.
Cross-sensitivities to other gases, and
damage to the sensor by typical poisons such as Silicone compounds or
Hydrogen Sulphide can be removed.
tive and powerful instrument, but
has also won design awards for its’
appearance, size and ease of use.
This was acknowledged by the Design
Centre NRW with the red-dot design
IR sensors are also not affected by
extremes of temperature and exposure to very high gas concentrations,
so working life and maintenance requirements are minimized. This gives
the use far lower servicing and op-
Field-proven features
Innovative alarm system
Alarm situations are notified with distinct multi-frequency alarm sounds.
The 103 dB(A) audible alarm is the
loudest available on the market today.
The unique “traffic light” visual alarm
of the G460 helps the user to quickly
and simply understand alarm status.
In alarm, the whole instrument display changes colour as shown below:

erating costs.
45 years data-logging capacity
The standard integrated memory records gas concentrations and alarms
detected at a 1 minute interval for
30 hours. This storage capacity can
be significantly increased by inserting an SD-memory card, which at
a data-logging interval of 1 minute
can store data for up to 45 years!
Therefore, for the first time, a lifetime
of worker´s exposure data can be
stored on one instrument.
Green
All gas values

range
An optional vibration alarm also increases the chances of the alarm
being acknowledged by the user.
Alarm limit values
Each channel (flammable, oxygen,
toxic) has 3 programmable alarm
values. In addition Occupational Exposure Limit (OEL), Time-Weighted
Average (TWA) and Short-Term Exposure Limit (STEL) are automatically
monitored and the average values
are stored. All alarm settings are
password protected, so that they
can only be configured by the appropriate person.
Intrinsically safe and water resistant
The G460 has a rugged, high-quality
rubberized housing and is shock resistant and water resistant to IP67.
Docking-station DS400
The DS400 docking-station is an
innovative instrument management
system, which can be used to check
and calibrate GfG detectors automatically. Instruments can be bump
tested or calibrated quickly and automatically, which substantially reduces
management time and costs. The
instrument is ready for use in no time.
The DS400 works auto-nomously (no
PC is required), and can be linked to
multiple docking-stations.
Compared with performing bump
testing and calibration manually, the
time taken and therefore gas used is
reduced by more than 50%, giving a
significant cost reduction. Bump test
and calibration status is easily seen,
and is “fool-proof” so user errors are
excluded. After each test there is
an indication of the result, “OK” or
“Error” according to the traffic light
principle – green means good, red
means stop. Data stored in the instruments can also be transferred to
an SD-card in the DS400, or to a PC.
Smart Pump G400-MP2
The smart high-performance pump
G400-MP2 can take gas samples
from distances of up to 100m. The
new pump communicates with the
gas detectors G450/G460 and allows fault indication via the detector
display. This is the perfect solution
for applications such as clearance
measurements of confined spaces,
tanks, basements, or trenches.
Accessories for every application
Mounting options
The G460 can be secured to the person using either a robust crocodile
clip, or a steel belt clip to ensure
hands-free operation in confined
spaces.
can be used to illuminate the water
surface, avoiding immersing the instrument in potentially damaging or
dangerous chemicals or sewage. The
existing battery unit of the G460 can
be replaced with an integrated lamp
battery unit if necessary. Thus, an
easy upgrade is guaranteed.
Flexible power supply
Also, the battery packs used in the
pump are directly interchangeable
with the instrument battery packs,
giving still more flexibility.
The G400-MP2 is the only attachable
pump available which may remain
fixed to the detector and provides
enormous flexibility.
When the pump is turned on the
diffusion inlets are covered and the
measurement results are not affected by air flows. An additional
filter system in the sampling line
protects the pump and sensors from
dust and moisture. When the pump
is turned off, the gas detector can
be operated as usual. The diffusion
inlets now allow all gases to enter
the sensor chamber. The G400-MP2
is operated on its own power supply,
independently from the gas detector,
i.e. the pump does not affect the
operational time of the G460 and
allows at least 10 hours of continuous operation.
Built-in flashlight
The G460 can be equipped with an
integrated ATEX approved flashlight.
This can be extremely useful when
working in dark, confined spaces.
Also, if the instrument is lowered into
a tank, sewer etc. to check the atmosphere prior to entry, the flashlight
The G460 NiMH-battery pack gives
an operation time of up to 30 hours
(depending on sensor configuration),
and minimum 8-9 hours. If battery
capacity is low, an automatic battery
alarm is triggered.
Drop-in charger
Intelligent charging technology
detects the battery condition and
provides a maximum operating
time while conserving battery life.
The drop-in charger communicates
with the gas detector. Even frequent
charging will be recognized and the
battery pack will not be over-charged
unnecessarily. For instruments with
an attached G400-MP2 smart pump,
a second charger is available in which
both, the instrument and the pump,
can be charged simultaneously.
Two smart caps
A smart calibration cap is used for
manual instrument calibration. A
smart charger cap (blue) is also available, which performs the following
functions:
■■ Gas calibration
■■ Location-independent charging
■■ Connection to 230V power supply
or
■■ Connection to 12/24V vehicle
charger
or
■■ Connection to a data cable for
data transmission
Vehicle charger for
12/24V
The G460 can be charged via the
smart charger cap, which is screwed
onto the instrument and connects
via a 12V plug or a cigarette lighter
socket in the vehicle.
Battery and battery packs with
additional features
An alkaline battery pack is available
for the G460, ensuring that work can
continue even if the user has not
charged the instrument.
The G460 battery pack can also be
supplied with vibration alarm, or
built-in ATEX approved flashlights
if required.
High performance sensors mean maximum safety
Multi-channel IR sensors
Using GfG´s unique, patented multiIR sensor both carbon dioxide (CO2)
and flammable gases can be measured at the same time. The IR sensor
uses up to 4 detectors.
Part of the IR radiation passes through
the measuring chamber once, then
meets the two detector elements
(D1, D2) to measure CO2 and e.g.
propane. For measurement of methane the IR radiation passes through
the measuring chamber twice and is
detected on two additional detectors
(D3, D4). For the first time, with only
one measuring chamber, it is possible
to detect CO2 concentrations from
ppm to %VOL range, in addition to
methane or other hydrocarbons from
the %LEL to %VOL range.
Photo ionization (PID) sensors
Volatile organic compounds (VOCs),
for example gasoline, diesel, fuel oil,
kerosene etc. are toxic and dangerous
to health even at very low (ppm) levels. These low detection levels cannot
be achieved by using a conventional
catalytic combustion sensor, which
detects flammable gas concentrations at the %LEL level. There are
STEL (Short-Term Exposure Limit)
and TWA (Time-Weighted Average)
exposure limits set by international
law for VOCs, some of which are at
concentrations below 1 ppm. The
GfG PID sensor can be used to detect hundreds of different VOCs. The
industry standard is that the sensor
is calibrated on isobutylene. Different
calibration gases can also be selected
by the user.
