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 microorganisms 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.

Case History 1 - Customer: Food Manufacturer (Sauces)


The company needed to be able to prove to the British Retail Consortium (BRC) that its cooking cycles had been completed correctly. Historically, this was done by manually recording temperatures from chart recorders or other devices and maintaining written records. The company also wanted to monitor temperatures in their chilled storage warehouse.


The RF500 System supplied can be programmed to provide independently variable logging rates for each individual transmitter, in line with the task being carried out. The single coordinated system has answered all the customer’s needs, including compliance with the company’s criteria which required 100% reliability in terms of logging rates and accuracy. The customer is also satisfied that all the data captured will stand up to scrutiny.


  • The ability to show that products have been cooked in accordance with customer’s instructions
  • Meets all data requirements for BRC auditing
  • Automated and consistent recordkeeping with little risk of human error

Case History 2 - Customer: A Chicken Processing Plant

The customer operates a chicken processing plant, with live birds in and packed, and processed raw chicken products dispatched.


To replace the current method of manually recording all HACCP and QA procedures which generates large amounts of paperwork.


A Comark N5001 HACCP Auditor has replaced all manual recording of HACCP and Quality Assurance actions throughout the site. This followed a detailed examination of existing paper based procedures - carried out by Comark - where methods were questioned and unnecessary checks removed. Comark then wrote a fully customized HACCP program, taking the user through all the required checks in the correct order and detailing corrective actions where required - it also allows management to spot nonconformances at a glance.


The N5001 HACCP Auditor has allowed the customer to greatly simplify their HACCP system. It has also been instrumental in the company passing its recent BRC audit. The auditor gave his personal approval to the use of the N5001. Two months after its implementation, the company increased production by 20%, and the time-savings resulting from using the N5001 have allowed them to do this without taking on extra QA staff.
