standard and fibroptic thermometers
STANDARD AND FIBROPTIC THERMOMETERS
INFRARED APPLICATIONS
Non contact temperature measuring systems are designed for
continuous quality and process monitoring and control in a wide
range of industries including Iron & Steel, Glass, Plastics, Rubber,
Minerals, Paper... and many more.
With measurement capabilities from 0 to 2600°C/50 to 4700°F,
infrared thermometers measure both the product being processed
and the plant and machinery used in the production. Here are just
a few of the processes where SYSTEM 4 can
solve your measurement problems.

There is a choice of thermometer type to match your temperature
requirements and process.
Single wavelength thermometers are intended for both general
purpose use as well as solving problems in specific applications.
Ratio thermometers are used in difficult environments containing
steam, smoke, or dust, or where the target does not completely
fill the field of view.
Fibroptic thermometers are used to measure the temperature of
materials where the target is difficult to access.
The use of fiber optics is most effective in high temperature, high
magnetic fields etc. which would prevent location of other sensors.
SYSTEM 4 THERMOMETERS
SYSTEM 4 comprises an advanced
range of high precision radiation
thermometers, LANDMARK® processors
and a range of mounting accessories
which combine to form a complete
temperaturemeasurement system.
SYSTEM 4 thermometers offer
exceptional flexibility with a choice of
single wavelength, ratio, fibroptic and
fibroptic ratio models.
Typical System
Thermometer type, temperature range, spectral
response and optical characteristics are chosen to suit
any application from 0 to 2600°C/50 to 4700°F
Focusable optics - standard and short focus
versions with through-the-lens sighting providing
clear and guaranteed definition of target
Optional close-up lenses - giving measurement of
targets as small as 0.45mm/0.02in
Accurate, reliable, drift-free measurement
Rugged design with a range of mounting options
Flexible fiber optics light guide versions - with
optional laser targeting system to define target
spot
High level linear output
RADIATION THERMOMETERS
Standard Bodied Thermometer
Fibroptic Thermometer
Proven, reliable electronics and a high quality optical system
combine to deliver accurate, dependable temperature
measurement. A rugged die-cast aluminium body, with a high
quality electrical connector, ensures reliable performance.
Standard bodied thermometers all feature through-the-lens
sighting with a 6° field of view. Adjustable focus with a circular
graticule gives precise alignment on to the smallest targets.
Two optical variants are available: Standard focus - adjustable
between 500mm/19.7in and infinity, and Short-focus - viewing
from 350mm to 1m/13.8 to 39.4in. Close-up lenses are also
available which can measure targets as small as 0.45mm/0.02in
from as close as 90mm/3.5in.
FIBROPTIC THERMOMETERS
The use of flexible fiber optics allows the detector and electronics
enclosure to be located in a less hostile environment, and
enables access to difficult targets.
The fibroptic thermometers are available with an optional integral
laser targeting system which defines the target spot for accurate
alignment.
The use of fiber optics permits viewing of normally inaccessible
targets, where there are high magnetic fields or in high ambient
temperatures up to 200°C/400°F without cooling of the optic
head. There is a choice of three optic heads and three light guide
lengths.

M2 Thermometers
M2 thermometers use the latest generation of germanium detectors
and operate at a wavelength of 1.6µm. They extend the measurement
range of short wavelength thermometers down to 300°C/600°F and
have a fast response time of 5ms.
M4 Thermometers
M4 short wavelength thermometers are used on low temperature,
low or uncertain emissivity surfaces such as bright or unoxidized
metals. They use lead sulphide detectors in a unique null balance
mode to guarantee stability. They have a response time of 100ms.
M5 Thermometers
M5 thermometers are specifically designed for glass surface
temperature measurement.
Fast speed of response, coupled with small target size and accurate
sighting facility make it ideal for all flat glass, glass toughening and
optical fiber preform applications.

ORDERING INFORMATION
SYSTEM 4 thermometers have a
unique part number to suit the particular
combination of features which make up the
model.
The model number, consisting of the
various options available, describes the
exact SYSTEM 4 thermometer type
required.
This model number can be used for
selection and ordering purposes.
For example: M1 600/1600 C - V describes
a single wavelength thermometer, operating
at 1.0µm, with a measurement span of 600
to 1600°, celsius version, with standard
variable focus optics.
