FULL UKAS - Calibrated - Fridge Thermometer - Max - Min Fridge - Calibration Certificate - MHRA - Digital Fridge

Although most commonly used to monitor the temperature of fridges our Fridge Thermometer with Max Min and Calibration Certificate can be used for a variety of applications such as monitoring room or warehouse temperature.

The fridge thermometer is  easy to read display shows you the current temperature of the room or fridge that you are monitoring as well as the minimum and maximum temperatures that have been reached.

To measure the temperature of fridges the thermometer probe should be placed inside the fridge freezer only and the main unit positioned outside.

The refrigerator thermometer has been calibrated to national standards using an independent calibration laboratory and is supplied with a traceable 3 point calibration certificate taken at 0°C,10°C,25°C FULL UKAS standards. This applies to the probe only.

The calibration certificate will be valid for no less than 10 months (unless otherwise advertised)

This max/min alarm thermometer simultaneously displays the actual temperature whilst displaying the maximum and minimum temperature.

The indoor/outdoor thermometer measures the grow room (in) temperature over the range of 0 to 49.9°C using the unit's internal sensor. Utilising the remote external temperature sensor the unit measures fridge or Room temperature over the range of -49.9 to 69.9°C.

Digital fridge thermometers features a programmable high/low temperature alarm that will sound when the pre-set limits have been exceeded.

The fridge thermometer is housed in an ABS case, measuring 20 x 65 x 97mm, that incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.

How often should you calibrate your fridge freezer thermometer
Calibrating your fridge thermometer - freezer thermometers are crucial to ensuring that your refrigerator is maintaining the correct temperature range. This is especially important if you are in the food or medical industry or if you have perishable items that need to be kept at a specific temperature. But how often should you calibrate your fridge thermometer?

The frequency of calibration largely depends on how often you use your fridge and your regulations also how much you rely on its accuracy. However, it is generally recommended that you calibrate your fridge thermometer at least once every year. This will ensure that your thermometer is accurate and that your fridge is maintaining the correct temperature range.

To test your calibrated fridge - thermometer, you will need a glass of ice water and a thermometer that is calibrated to measure temperatures between 0 and 10 degrees Celsius. Fill the glass with ice and add water until it reaches the top. Stir the mixture and let it sit for a few minutes until it is completely chilled. Place the thermometer in the ice water, making sure that it does not touch the sides or the bottom of the glass. The thermometer should read 0 degrees Celsius. If it does not, adjust the calibration until it does. This method does not calibrate the thermometer only checks the thermometer.

It is also important to note that if you notice any fluctuations in the temperature of your fridge, you should calibrate your thermometer immediately. Fluctuations in temperature can be caused by a number of factors, including a faulty thermometer, a clogged condenser, or a malfunctioning compressor. Calibrating your thermometer can help you identify and address these issues before they become more serious.

In summary, calibrating your fridge thermometer at least once every year is recommended to ensure that your fridge is maintaining the correct temperature range. If you notice any fluctuations in temperature, calibrate your thermometer immediately to identify and address any issues.

Calibration length will very much depend on your own risk assessment and regulations

Can also be used in a freezer.

Traceable or UKAS Calibration?

Traceable or UKAS Calibration?

Absolute Calibration UKAS ISO17025 accreditation assures the customer that all measuring equipment has an unbroken chain of traceability back to national standards, therefore by definition all calibrations performed by Absolute Calibration are traceable to national standards. If your quality assessor asks you to demonstrate traceability, you have already achieved this by using Absolute Calibration.

In our experience there is increasing confusion over whether companies require UKAS calibration certificates or calibration certificates traceable to national standards.

Still confused then check out Absolute Calibration Guide to calibration click here

If your quality assessor instructs you to have your instruments calibrated to UKAS, please ask if that means an actual UKAS calibration certificate or traceable to national standards. If you are unsure please check with the governing body of your industry. If your customer or regulatory body does not require you to have a UKAS calibration certificate then it is up to you to decide if which type of calibration satisfies your production and quality requirements.
