Customer Message - Disruption due to Coronavirus *** Updated 25/03/20 ***

We are currently operating with a minimum of essential staff. Whilst we continue to dispatch orders, we would be grateful if customers would bear with us. Orders are being dealt with on a strict first come first served basis, but we cannot guarantee dispatch or delivery will meet our usual standards.

If ordering from us, please note:
  • 1. Our couriers are suffering from higher demand and are struggling to meet their delivery targets. We can therefore not guarantee delivery service lead times, particularly if you choose the Overnight or Express options.
  • 2. We are no longer able to process orders for bespoke items, including garment embroidery.
  • 3. We are unable to answer telephone enquiries. If you need to contact us, please email.
We would like to wish all our customers the very best in these difficult times and hope you manage to stay safe and healthy.

Further Information

The fridge thermometer is also sometimes referred to as a chiller thermometer, coldroom thermometer or refrigerator thermometer.

Harmful bacteria will grow rapidly if chilled food is not kept at the correct temperature. We offer a large range of thermometers designed for fridges (refrigerators), freezers, chillers, cold rooms and larders which will help to ensure food is kept out of the "danger zone".

Our thermometers include colour-change, spirit-filled, bimetal strip and digital instruments.

The traditional fridge thermometer is now filled with spirit rather than mercury, which has now been banned for all but laboratory use. They are available in a number of styles but all clearly show the correct storage temperatures for fridges and freezers.

A dial thermometer relies on a bimetal strip to move the needle to the correct temperature. This strip is wrapped into a coil with one end of it being attached to the thermometer casing and the other attached pointer. The strip is actually made from two separate strips of different metals, usually steel and copper. These metals will expand at different rates as they are heated with the metal that expands most on the outer side of the coil. As the strip warms up the metal will bend in one direction and in the other direction when it cools. Although our dial thermometers are available in different casing, plastic, stainless steel etc the technology behind them is the same.

The Thermometer Superstore range of fridge freezer thermometers also includes digital instruments. The sensor for the thermometer is placed inside the fridge or freezer and the digital display is left outside. This way the user can check the internal temperature of the fridge/freezer with having to open the door (and let in warm air).

A digital thermometer will not only provide accuracy but many have additional features such as recording the maximum and minimum temperatures which gives reassurance that the appliance has been operating correctly over a period of time and alarms which will warn when the temperatures goes above a pre-set maximum.
