Stop! Think how your business could benefit from BioCote protected instruments. ®
As an extra level of defence against crosscontamination, all the latest Comark instruments are manufactured with BioCote® antimicrobial technology impregnated into the instrument surfaces, keypads and probe handles. The technology utilizes silver, a natural antimicrobial that helps prevent the growth of bacteria, mould & fungi and lasts for the life of the instrument. When micro-organisms come into contact with the silver, their ability to reproduce is inhibited and they die. A recent trial by BioCote Ltd and The University of Wolverhampton Science Park
canteen was 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. 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 any doubt that BioCote® protected instruments are significantly cleaner and safer to use in sensitive environments.
The actual result was a massive 92.73% reduction in microbe levels!
Only Comark offers thermometers with Biocote antimicrobial technology ®
Premium Thermometers For temperature measurement applications when only the best will do. These premium thermometers provide excellent accuracy and incorporate a range of advanced features designed to answer the quality control and HACCP requirements of the professional user. These include a permanent clock and countdown timer within the display – with selectable alarms – to allow probe insertion times and cooking and cooling times to be monitored. All three models have BioCote antimicrobial impregnated into the instrument surfaces for increased protection against cross-contamination – see page 9 for more details. ®

Infrared Thermometers For safe, non-contact surface temperature measurement.
Non-contact temperature measurement is a useful tool throughout the food industry. Apart from reducing risks from crosscontamination, non-contact also means less waste as it avoids destructive tests on valuable products. Infrared thermometers allow quick non-contact temperature checks to be carried out and if a problem is identified, further investigation can be undertaken using a penetration probe. Comark offers two infrared thermometers, FoodPro and FoodPro Plus. The following features apply to both. • Indicator lights to warn of potential problems • Illumination light identifies target area • IP54 rated hand washable instrument case • Switchable °C / °F scales • 7 second hold on the display, with auto switch-off
FoodPro Infrared thermometer Simply point the instrument at the area to be measured and read off the temperature on the display. • Measurement range: –30°C to + 200°C, switchable to °F • Accuracy for targets at –30°C to +65°C: 1°C • Accuracy for targets above 65°C: ±1.5% of reading Order code: FP
2 YEAR WARRANTY FoodPro Plus Combined infrared and probe thermometer Similar to the FoodPro but with a wider infrared temperature range, a countdown timer and a flip-down penetration probe for more accurate confirmation of temperature where a potential problem has been identified. • Measurement range (infrared): –35°C to +275°C • Measurement range (probe): –40°C to +200°C • Infrared accuracy for targets at –30°C to +65°C: 1°C • Infrared accuracy for targets above 65°C: ±1.5% of reading • Probe accuracy between –18°C and +65°C: ±0.5°C Order code: FPP

Choosing a Temperature Probe A comprehensive range that covers virtually every temperature measurement application.
Comark produces one of the largest available ranges of temperature probes, with a probe for almost every application. There is a special probe design and build facility so if you can’t find what you need within the standard range, Comark can either modify an existing probe or supply probes to customer designs.
Probe Categories
Choosing the right sensor
Comark standard probes fall into four main categories and each includes probes with different sensor types: Penetration probes are used for measuring the internal, or core temperatures, of solid and semi-solid materials. Surface probes are designed for maximum contact with the surface to be measured. Air probes are for measuring air and gas temperatures, but also include food simulant and damped sensor probes. Immersion probes measure the temperature of liquids and semi-solids. Where required, UKAS certificates of calibration can be provided for probe and thermometer combinations.
The choice of sensor will determine the measurement range, the accuracy and the response time. The sensor type must also be compatible with the thermometer you use. Comark standard probes use two basic sensor types: 1. Thermocouples. These consist of two wires made of dissimilar materials joined together at the measurement tip (the hot junction) and connected at the other end to the instrument (the cold junction). The two main thermocouples used in Comark food thermometers are Types K and T. See opposite for thermocouple limits. The Type K Thermocouple has a wide measurement range, responds quickly to temperature changes and is suitable for general food applications. The Type T Thermocouple also responds quickly to temperature changes and generally provides greater accuracy, but it is effective over a narrower temperature range. 2. Thermistor (PST) is a semi-conductor sensor and provides exceptional accuracy but over a much narrower temperature range.
22
Choosing the right probe Within the Comark standard probe range you’ll find probes for general duties as well as ones for more specialist applications. Try to match the probe to the job. For example, a low mass flexible air probe is better suited to accurate air temperature measurement than a penetration probe which will take too long to stabilise. For solid and semi-solid materials use surface probes for surface measurements. Specialist options include probes with a rigid flattened stem for sliding between packs of frozen foods on a pallet or a specially weighted griddle probe to ensure consistent cooking temperatures. Use penetration or immersion probes to check internal temperatures. Where holes need to be drilled in solids, use a thermocouple or thermistor probe and make sure it’s inserted to at least 6 times its
diameter. You can also use a thermal transfer compound for improved accuracy. Alternatively a corkscrew probe may be most appropriate. For liquids use an immersion probe, or you can use certain penetration probes, but check for possible corrosive effects on the sensor first and agitate the liquid for a faster response. For air and other gasses use an air probe. Response times are affected by heat transfer around the sensor, and the smaller the sensor, the faster the response time. Response is also affected by air movement. Food simulant and damped sensor probes have a large mass around the sensor to slow response times so they don’t trigger alarms when fridge or freezer doors are opened or during defrost cycles.

Probe Leads Comark probe leads are matched to the intended applications for the probe. The materials used are: PVC – PVC coiled leads provide ease of use in ambient temperatures of up to +70°C. FEP and PTFE – These materials are especially suited to food probes and can be used in sub-zero temperatures. Steel braided PTFE leads provide greater strength. Fibreglass (FG) – Fibreglass insulated leads are used for special application probes where the lead could be subjected to very high ambient temperatures of up to +400°C.
