ETI ThermaGuard Fridge Thermometer with UKAS Certificate - Single or Dual External Sensor

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

The internal sensor on the ThermaGuard 101 (891-511) measures temperature over the range of -19.9 to 49.9 °C, while the external sensors measure over the -39.9 to 49.9 °C range. Both have an accuracy of ±0.4 °C and a resolution of 0.1 °C/°F. With a 25000-hour battery life (regular use, without alarm), the 1.5 volt AA batteries will only need changing every 34 months.

The digital fridge thermometer incorporates a large LCD that 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.

The ThermaGuard is encased in a splashproof IP54 ABS case which includes Biomaster antimicrobial technology that reduces bacterial growth, ideal for monitoring chilled and frozen foods.

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 at any time, giving confidence that measurements are accurate.

Free Wall Bracket

Each ThermaGuard includes 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 and securely and protect against accidental damage.
