ADR – Automatic Data Retrieval.
The RF500A employs a system of remote
sensors and probes to automatically collect
and transmit data to a Gateway unit which
manages the system and stores the data.
In the event of a power failure, data is
stored in the RF500A transmitter then
automatically transmitted to the Gateway
as soon as the network is restored, so no
data is lost.
The RF500A Gateway requires no
specialist PC software. It connects directly
to the local area network permitting 24/7
single or multi-user access via the internet
at any time. The system provides a full
audit trail, electronic signatures and data
protection to meet the requirements of 21
CFR Part 11.
In the event of readings falling outside
pre-set limits, alarm notification via
screens, SMS, email or voice contact you
immediately, so immediate corrective
action can be taken.

Temperature & Humidity Data Loggers
Diligence WiFi Data Loggers from Comark provide an easy
way to collate temperature data automatically, 24 hours a day,
seven days a week. For any organisation involved in providing
or serving food to the public, it provides critical visibility of food
safety compliance.
New!
Manual temperature collection takes valuable time which could
be saved by automation and it also removes the risk of mistakes.
An audible alarm provides an alert whenever temperatures fall out
of range of preset conditions so corrective action can be taken
before valuable stock is put at risk.
As soon as the Diligence WiFi network is set up, temperature or
humidity is continually logged and data is transmitted wirelessly
via your existing WiFi network to a PC and viewed using the
free Diligence WiFi secure software package. When installed the
software allows set-up, data logging and data review. Historic data
can be viewed via the graphing tool or exported to Excel.
Use Diligence WiFi Loggers to monitor areas such as walk-in
and reach-in refrigerators and freezers, cold storage areas, blast
chillers, and hot holding cabinets.
• RECHARGEABLE. A full charge lasts 3-12 months
• Easy to self install out of the box
• Connects to existing WiFi networks, no hard wiring required
• Quick to mount in any location
• Use Diligence WiFi secure software to view data and report
• Reliable temperature data 24 hours a day, 7 days a week
• Built-in visual WiFi Signal Meter

for gauge or differential pressure and positive
or negative (vacuum) pressure measurement.
These instruments are ideal for applications like
H & V, process pressures, laboratories and clean
rooms, through to service and maintenance and
the calibration of other instruments.
The C9500 range is identical to the above
in terms of specifications but all instruments
are ATEX certified Intrinsically Safe (I.S.) for
working in hazardous environments. Certified to
II 1 G EEx ia IIC T4 Baseefa03ATEX0079.
All C9500 models also have average reading
function and over-range indication.
The C9550 offers silicone protection as an option. This
allows liquid pressures to be measured without the risk
of sensor corrosion. Simply order the version with ‘SIL’ in
the order code.
Four models are offered in each range with measurement
parameters 0 to 2PSI, 0 to 5PSI, 0 to 30PSI and 0 to
100PSI. Readings can be displayed in up to 11 different
scales depending on the model. See table for options.

Calibration Instruments
Temperature and measurement
instrument performance is vital
in almost every application,
especially throughout the
food industry.
Performance can be affected by many factors
including use and abuse and the age of the
instrument. Regular, professional calibration
checks are recommended, with certification as
required, especially for companies with HACCP
procedures and other quality systems. In the
meantime, calibration can be monitored with
Comark simulators, reference thermometers and
validation equipment.

conducted to compare micro-organism levels on
a BioCote® treated Comark thermometer with an
untreated thermometer. The trial was carried out
over an 8 week period.
The technology utilises silver, a natural
antimicrobial that helps prevent the growth of
bacteria, mould and fungi and lasts for the life of
the instrument. When micro-organisms come into
contact with a Biocote® protected surface their
growth is inhibited, reducing microbial populations
resulting in a more hygenic product.
Swabs were taken from the thermometer case,
keypad and probe handle before and after each
use and the number of contaminating bacteria
was counted. The treated instrument showed
a dramatic reduction in microbe levels, proving
beyond doubt that BioCote® protected instruments
are significantly cleaner and safer to use in
sensitive environments.
A trial by BioCote Ltd and The University of
Wolverhampton Science Park canteen was
The actual result was a massive
92.73% reduction in microbe levels!

Temperature Probes
Comark produces one of the
largest available ranges of
temperature probes, with a probe
for almost every application.
Comark can certify temperature probes, either alone,
or, as recommended, with an instrument to record system
accuracy. Certificates of calibration are supplied through
the Comark in-house UKAS accredited temperature
calibration laboratory and the in-house NPL
traceable laboratory.
The Comark Service Team or your local distributor can
offer advice on probes and certification and can provide

FORMULA
GLOSSARY OF TERMS
ATEX: Atmosphére Explosive. Refers to the current
standards for Intrinsically Safe equipment.
Baseefa: Refers to Baseefa 2001 Ltd, the notified body
for Comark ATEX compliance.
Differential Measurement: Ability of an instrument
to measure temperature, pressure etc. simultaneously
from two different points and to calculate the difference
between them.
Distance to Spot Size Ratio: The measure of the
increase in the target area diameter detected by an
infrared thermometer, over the distance from instrument
to target surface.
Emissivity: The natural level of infrared radiation from
the surface of any material. Emissivity is measured on a
scale from 0.1 to 1.0, where 1.0 represents the radiation
from a black body.
HACCP: Hazard Analysis and Critical Control Point.
The quality system used throughout the food industry to
ensure safe food.
HVAC: Heating, Ventilating and Air Conditioning.
IP Rating: Set of standards for dust and waterproof
protection. Many Comark instruments are rated at IP67.
Lumberg: Connector with locking screw, used to provide
strong, secure probe-to-instrument connections with
better prevention of liquid ingress.
NPL: The National Physical Laboratory.
Operating Range: Temperature and humidity limits
within which an instrument will function correctly.
Pt100: Platinum resistance thermometer. High accuracy
temperature sensor.
“Quick” Calculations: Pre-programmed calculations
available in software, such as average or standard
deviation.
Resolution: Indicates the smallest difference in
measurements that can be detected and displayed by
the instrument, e.g. 0.1° indicates that the instrument
can detect differences of one tenth of a degree. In some
cases there can be a difference between the detected
measurement change and the displayed change.
Sub–miniature: Two-pin industry standard connector.
System Accuracy: Temperature accuracy level for the
instrument and probe combined. Instrument accuracy
excludes the probe.
Thermistor: Type of temperature sensor offering
accuracy suitable for food applications.
Thermocouple: Type of temperature sensor using
bi–metal electrical properties. Eight types of bi-metal
combinations are available: – K, N, T, J, R, S, E and B –
with different measurement ranges and characteristics
to suit different applications.
UKAS: The United Kingdom Accreditation Service.
Wraparound: Ability to program a data logger to
continue logging when its memory is full, by logging new
readings over the oldest readings already in the memory.
