The ThermaGuard Fridge Thermometer is a high accuracy fridge freezer thermometer that is available in two models for varying sensor needs. Essential for food safety, the max/min, alarm and CalCheck functions make this model a great option for HACCP compliance.

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

With a 25000 hour battery life (normal use, without alarm) the 1.5 volt AA batteries will only need changing every 34 months. 

The digital fridge thermometer is housed in a splashproof IP54, ABS case which incorporates a large LCD display, and simultaneously displays the current and max/min recorded temperatures. Both models also feature programmable alarms to give you an audible warning if the temperature of your fridge or freezer falls outside the safe temperatures you set.

Each ThermaGuard is . 

An optional two-point (-18, 0°C) UKAS Certificate of Calibration is available. Each certificate indicates deviations from standards at -18 and 0 °C. *UKAS certificate applies to remote probes only

Two models available

The ThermaGuard 101 incorporates two temperature sensors; a remote water-resistant temperature probe with a two-metre PVC lead for monitoring the appliance temperature and an internal sensor for the room temperature.

The ThermaGuard 102 incorporates two remote water-resistant probes, both with two metre PVC leads for monitoring two appliances. Each remote probe can be mounted onto the internal wall of the fridge using the small ABS plastic mounting bracket supplied. 

CalCheck function

Both models of the ThermaGuard feature a CalCheck 0.0 °C (±0.1 °C) function that allows the user to verify the accuracy of the thermometer at any time, giving confidence that measurements are accurate.

Free wall bracket

Each ThermaGuard is supplied with a plastic wall bracket that incorporates a built-in foot stand, hook for hanging and screw thread for tripod mounting, allowing users to store or position the unit safely, securely and protect against accidental damage.
