Traceable® Ultra™ Refrigerator/Freezer Thermometer, 1 Bottle Probe

The Traceable® Ultra™ Refrigerator/Freezer Thermometer is a precision digital thermometer designed for accurate temperature monitoring in refrigerators, freezers, water baths, and incubators. The thermometer features a triple display that simultaneously shows current, minimum, and maximum temperatures. The glass bottle probe is filled with a nontoxic glycol solution (GRAS) that mimics the temperature of stored liquids, providing a temperature‑buffered measurement. The probe includes a 10‑ft microcable that allows refrigerator and freezer doors to close without compromising the seal. Built‑in audible and visual alarms activate when temperatures rise above or fall below programmable set points (in 0.1° increments) and continue to alarm until acknowledged. The thermometer includes an individually numbered NIST‑traceable certificate from the manufacturer's ISO/IEC 17025:2017 (1750.01) accredited calibration laboratory.
