Fridge & Freezer Calibration Service

It’s often very important not to wait too long to calibrate your equipment. The temperamental nature of food means that accurate readings are a necessity. If your fridge calibration is not done, then there is a high chance that the improper readings will lead you to store food beyond its expiry or even in a manner that does not keep it fresh. This effectively means that without professional freezer calibration you are likely to pose a dangerous risk to your employers or family by storing food at non recommended temperatures.

Frequently Asked Question's

In order to have a perfectly calibrated temperature and humidity meter, many experts recommend using something known as the salt method. This involves placing the hygrometer into a sealed container along with a teaspoon of salt with a few added drops of water. Then after letting them both sit for six hours, your hygrometer should read 75% in humidity. It should be noted that this method is not as reliable as a professional thermometer calibration service.
Comprehensive humidity meter calibration requires the creation of a unique chamber known as a humidity generator. This allows you to create a specialised temperature and humidity within a given space and then compare the results of the device with the humidity and temperature chart recorder. This kind of testing is best done in a lab which is why one should approach a professional thermometer calibration service provider.
