Refrigerator/Freezer Alarm Thermometers

Fisherbrand™ Traceable™ Refrigerator/Freezer Alarm Thermometer – Bottle Probe, ±0.5°C Accuracy

Reliable Temperature Monitoring with Buffered Sensor for Cold Storage Applications

The Fisherbrand™ Traceable™ Refrigerator/Freezer Alarm Thermometer provides accurate, real-time monitoring of cold storage environments using a temperature-buffered sensor sealed in glycol solution. Ideal for freezers, refrigerators, incubators, water baths, and heating blocks, this thermometer ensures stable readings even when doors are opened, minimizing false alarms.

Equipped with a triple display, it simultaneously shows current, high, and low temperatures, and includes visual and audible alarms that activate when temperatures deviate from user-defined setpoints. The 10 ft (3 m) micro cable allows the probe to remain inside while doors close securely.

Certified to ISO 17025, A2LA, and NIST standards, this unit features ±0.5°C accuracy, 0.1° resolution, and comes calibrated for immediate use. The compact design includes Velcro™ and magnetic mounting, a AAA battery, and a durable ABS plastic case.
