Q & A


Why do I need to use a calibrated thermometer?

The use of a calibrated thermometer/probe is required under Section 3.4 of I.S. 340:2007

Why do I need to have my thermometer calibrated every year?
Regular calibration is required under Section 3.4 of I.S. 340: 2007. All thermometers are subject to drift and therefore require calibration to ensure that they remain within their stated accuracy. Annual calibration by an external laboratory backed up by regular in-house accuracy checks has become industry standard – recommended by manufacturers and expected by regulatory authorities.

Do I need to carry out in house accuracy checks on my thermometers?
Yes regular accuracy checks of all temperature probes in use is required to ensure that they are within their accuracy specification and to comply with Section 3.4 of I.S. 340:2007

How should I care for my thermometer?

Digital thermometers and their probes need careful handling at all times to ensure a long life and to prevent probe damage.


  • Care should be taken when disconnecting the probe from the instrument (Only applicable if probe is removable)
  • Always store your thermometer and probe in a dry,safe place
  • In the interest of hygiene, clean the probe before and after each use
  • Always use the correct probe for the type of measurement being taken


  • Never drop the instrument or lift the instrument by the lead or probe
  • Never submerge the instrument and probe in water or other liquids/solutions
  • Do not disconnect the probe from the instrument by pulling the cable (Only applicable if probe is removable)
  • Do not wrap the cable around the instrument

How should I monitor the temperature of our fridges/cold rooms/freezers?

There are a variety of ways of monitoring the temperatures in the product storage areas of this type of equipment. The method selected will primarily depend on the size of your facility. Temperatures can be monitored manually using a hand held thermometer with an air probe, the operator manually recording the results – the pen and paper method. This job is time consuming, does not give continuous temperature readings and manual records are becoming less acceptable to the regulatory authorities. Temperature Data Loggers record temperature, date and time and can be configured to record at intervals of I minute upwards. The temperature data is transferred to a PC/IT system for viewing, reporting, archiving etc. The data is transferred to PC either by connecting each data logger to the PC or, with automatic systems, the data logger will transmit the data to the PC either on a wired or wireless system. The fully automatic systems are configurable to send out of hours alerts of temperature excursions.

Is it possible to receive out of hours alarm alerts for cold rooms and freezers?

Yes using our wireless temperature monitoring system, alarm alerts by text / email may be received, when temperatures go outside set parameters
