ThermaGuard Digital Alarm Thermometer for Refrigerators and Freezers

The ThermaGuard refrigerator thermometer is a highly accurate thermometer designed for fridge-freezer combinations, available in two models to suit different sensor requirements. Its max/min, alarm, and CalCheck functions are essential for food safety, making this model an excellent choice for HACCP compliance.

The internal sensor (model 101 only) measures temperatures between -19.9 and 49.9 °C, while the external sensors measure temperatures 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 (under normal use, without the alarm), the 1.5V AA batteries only need to be replaced once every 34 months.

The digital refrigerator thermometer is housed in a splash-proof IP54 ABS casing with a large LCD screen that displays both the current temperature and the maximum and minimum temperatures recorded. Both models also feature programmable alarms that emit an audible signal if the temperature of your refrigerator or freezer falls outside the safe range you have set.

The ThermaGuard 101 is equipped with two temperature sensors: a water-resistant external temperature sensor with a two-meter PVC cable for monitoring the device’s temperature, and an internal sensor for room temperature.

CalCheck feature

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

Free wall mount

Every ThermaGuard comes with a plastic wall mount featuring a built-in base, a hook for hanging it, and a threaded mount for attaching it to a tripod. This allows the device to be stored safely and securely and protected from damage.
