ThermaGuard Digital Refrigerator and Freezer Alarm Thermometer

The ThermaGuard refrigerator thermometer is a high accuracy fridge freezer thermometer, available in two models to suit different sensor needs. The max/min, alarm and CalCheck functions are vital for food safety and make this model an excellent choice for HACCP compliance.

The internal sensor (model 101 only) measures temperature between -19.9 and 49.9 °C, while the external sensors measure between -39.9 and 49.9 °C. Both sensors have an accuracy of ±0.4 °C and a resolution of 0.1 °C/°F.

With a battery life of 25,000 hours (normal use, without alarm), the 1.5V AA batteries only need to be replaced once every 34 months.

The digital fridge thermometer is housed in a splash-proof IP54 ABS case with a large LCD display that simultaneously shows the current and the measured max/min temperature. Both models also feature programmable alarms that provide an audible signal if your fridge or freezer temperature falls outside your set safe temperatures.

The ThermaGuard 101 features two temperature sensors: a water-resistant external temperature sensor with a two-meter PVC cable for monitoring appliance temperature and an internal sensor for ambient temperature.

CalCheck function

The ThermaGuard incorporates a CalCheck function with an accuracy of 0.0 °C (±0.1 °C). This allows the user to check the accuracy of the thermometer at any time, ensuring that the readings are correct.

Free wall bracket

Each ThermaGuard is supplied with a plastic wall bracket that incorporates a built-in foot stand, a hook for hanging, and a screw thread for tripod mounting. This allows the device to be stored securely and protected from damage.
