Diligence and EVt loggers, and the new
BT250KC wireless system – offer accurate
and tamperproof 24/7 recording of key
parameters to augment your HACCP and
food safety program.
Designed especially for the food industry
Comark instruments meet a number of
key international standards:
• Most of our key products are NSF
certified so you can trust that they
meet their published accuracy and
specifications. Every component is
food grade and manufactured in a
sanitary facility.
• The CE mark certifies that the product
meets European health and safety
regulations.
Many Comark products are molded
with BioCote®, a patented silver-based
antimicrobial agent. BioCote® effectively
inhibits the function, growth, and
reproduction of a wide range of microorganisms. Its protection is increasingly
accepted as part of HACCP, due diligence
and health and safety procedures.
BioCote® protection lasts for the life of
the instrument because the agent is
present throughout the case plastic and
cannot rub off or leach out. The active
ingredients are registered with the EPA.
With our wide range of products, a
knowledgable staff and a commitment
to your satisfaction, you can count
on Comark for answers to all of your

Diligence WiFi
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 organiation
involved in providing or serving
food to the public, it provides critical
visibility of food safety compliance.
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.

Pressure Meters
Accuracy and
speed of response,
plus ATEX certified
Intrinsically Safe
options are the
factors which define
Comark pressure
meters.
The C950x range of pressure meters is suitable 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 C955x 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 C95xx models also have average reading function and overrange indication. The C95xx/SIL 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.

Warranty
All Comark instruments have a minimum one year warranty unless otherwise stated. The
warranty for temperature probes is six months and all other probes are unwarranted because the
conditions of use are beyond our control. The Comark Warranty covers manufacturing defects and
component failure and applies worldwide. In line with our policy of continuous development, we
reserve the right to alter any product specification without notice. Comark has an accredited UKAS
(NIST equivalent) calibration laboratory for temperature and humidity measurement and offers full
service and recalibration facilities.
Comark products are designed and manufactured for commercial use by trained operators. Any
reference to ‘dishwasher safe’ refers to commercial machines, not domestic or home model
machines. Waterproof denotes that an item can be used in the wet environment of a commercial
establishment. Comark thermometers are not designed for use underwater.
Comark Instruments is committed to providing quality and affordable products to the food service
industry. Our thermometers and humidity testers bring speed, accuracy and reliability to the
