Food Retail & Supermarkets

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.

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.

Infrared thermometers and between-pack probes are widely used to quickly and accurately check chilled and frozen deliveries without damaging packaging.

The best HACCP thermometer is the Thermapen ONE.

• High accuracy — Accurate to ±0.3 °C (-19.9 to 119.9 °C) for food safety. Free traceable calibration certificate included.
• Instant readings — Reads in only 1 second, ideal for busy kitchens.
• Long guarantee — Protected for 5 years.
• Hygienic design — IP67 waterproof for easy cleaning. Biomaster antibacterial additive prevents bacterial growth. Hygienic button-free operation.
• Intuitive display — Auto-rotating, backlit screen for easy reading in either hand and any lighting.
• Made in Britain — Designed and made in the UK. Loved by professional chefs worldwide.

Remote systems automatically record temperature data at critical control points. This creates clear, auditable records and helps demonstrate compliance with HACCP requirements.

Calibrate your instruments and probes at least once a month, or more if they are used heavily, accuracy is critical, or you are using them in a harsh environment.

Check the accuracy using an ice bath test or other form of calibration equipment.
If the equipment is outside of its specified range, you can return it to us for recalibration at our UKAS-accredited laboratory.

Don’t forget to record your calibration processes and results for your HACCP plan.

• Speed — Working in a busy food service environment? Choose a fast-reading probe that reads in under 3 seconds, such as the Thermapen ONE or Classic models.
• Accuracy — If accuracy is critical to your operations, choose a high-accuracy model, such as the Therma 20 thermometer, which offers a guaranteed system accuracy of ±0.5 °C for life.
• Probe type — If you only need to measure core food temperatures, a thermometer with a permanently attached food probe (such as a Thermapen or Food Check) is a good choice. If you would like to use your thermometer for multiple checks, such as between-pack delivery temperatures and air temperatures in fridges/freezers, thermometers like the Therma 20 allow you to switch probes for different applications.
• Environment — Working in a harsh food processing environment? Robust and waterproof thermometers like the Therma 20 Metal are built to withstand moisture, corrosion and impact.

The ETI Fridge Freezer Wireless Temperature Monitoring Kit is the best choice for cold storage.

• High-quality data logger — The ThermaData 2-Channel WiFi Data Logger is designed and made in Britain and built for accurate, long-lasting measurements.
• Dual monitoring — Two probes for tracking two fridges or freezers at once. Slow-response probes mimic food temperature for more accurate results.
• Free software — Monitor readings remotely, build reports, and get push notifications when limits are exceeded.
