Keep chilled or frozen foods within acceptable food safe limits with ThermaGuard. With programmable alarms and high accuracy to ±0.7°F (±0.4°C), your critical inventories are maintained well within food code requirements. Install ThermaGuard confidently with its NIST-traceable calibration certificate, so you know that your readings are accurate.

Set high and low audible alarms with the easy up and down buttons. Constant Max and Min displays make sure you know when danger-zone limits have been breached and how high or low your fridge or freezer temperatures traveled.

Select from two models: model 101 includes two sensors – one internal ambient sensor and one external probe with cable. Choose model 102 for monitoring with two external probes (for example, one for your fridge and one for your freezer). Probe cables are 3-feet long (1m) and waterproof making it easy to mount the probes inside your fridge or freezer while the main unit display is viewable outside on a walk-by audit or line check.

ThermaGuard ships with a handy wall bracket that doubles as a counter stand for easy viewing of temperature data. Mount probes with included suction cup holders or plastic mounting brackets for optimal performance.

ThermaGuard is splash-proof with an IP rating of IP54 with an extra-long battery life of 3 years installed with standard AA batteries. Both models feature a CalCheck feature that performs a quick accuracy check of the electronics so you'll know it's accurate.

ThermaGuard is a professional instrument made in the UK in a high-quality instrument shop with over 35 years of manufacturing and calibration experience. With best-in-class performance, be confident about your fridge and freezer's performance with ThermaGuard.
