Fridge & freezer thermometers

Digital fridge freezer thermometers, wireless instruments and budget-friendly dials for keeping cold food stored safely.
Fridge & freezer thermometers

UK food companies are legally required to store cold food at a temperature of 8 ˚C or below. They must therefore monitor cold fridge and freezer temperatures to comply with health and safety procedures such as HACCP.

ETI offer a range of digital fridge freezer thermometers to suit every budget and application. This ranges from simple fridge or freezer thermometer probes with audible alarm functions to fridge freezer data loggers which will provide digital alerts for out-of-range temperatures. This will ensure food is safe to consume whilst protecting catering businesses from costly food spoilage.

Pharmaceutical businesses are also required to store certain vaccinations and medicines at specific temperatures so they are safe to use. ETI’s ThermaGuard Pharm thermometers are ideal for this, with medical fridge thermometer and lab refrigeration data logger options available.

Frequently Asked Questions

What is the best way to monitor fridge temperatures?

There are a few ways to monitor fridge temperatures depending on budget, accuracy requirements and the size of your business.

Analogue fridge thermometers — Simple, budget friendly dials for routine checks.

Digital fridge thermometers — More accurate and easier read than dial thermometers, often with audible high temperature alarms.

WiFi data loggers — Automated fridge temperature recordings. View readings off site and get push notifications for high temperatures anytime, preventing stock spoilage.

What is the best way to monitor multiple fridges across different retail store locations?

WiFi loggers enable users to monitor multiple fridges and freezers across different sites all in one place.

ETI's ThermaData WiFi loggers take automatic readings at timed intervals, sending the readings to ThermaData Hub software for remote monitoring and reporting. The software also pushes notifications through to the TD Link app on multiple mobile devices, so staff can be notified if temperatures drop anytime, anywhere.

What temperature should fridges and freezers be?

In the UK, food in commercial fridges must legally be kept below 8 °C. For optimal quality and freshness, it is recommended to keep cold food at around 5 °C.

Frozen food should be kept at -18 °C or below.
