Traceable® Refrigerator/Freezer Thermometer Complete Description

Accurately monitor temperatures in freezers, water baths, heating blocks, incubators, and refrigerators with this enclosed “temperature-buffered” sensor. Bottle insulates sensor from rapid temperature changes when refrigerator door is opened. Thermometer fulfils all CDC thermometer and vaccine thermometer requirements.

Records high/low readings

Triple display simultaneously shows high, low, and current temperatures. Min/max monitors high/low readings overnight, on weekends, or for any time period—a significant advantage over “current reading-only” glass thermometers. Range is –58 to 158°F and –50 to 70°C with a resolution of 1° and accuracy of ±1°C.

Signals out-of-range conditions

Alarm feature provides alert when temperature rises above or falls below a set point. Alarm is programmable in 1° increments. Visual and audible signals continue even if temperature returns to non-alarm range. Ten-foot micro-cable permits refrigerator doors to close on it.

Avoids Contaminants

Solid-state probe eliminates mercury contamination in refrigerators. Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with patented nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water.

Traceable to NIST for accuracy

To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). High-impact, chemical-resistant ABS plastic case is 2-3/4 x 4-1/4 x 3/4 inches. Weight is 4 ounces. Velcro™ and magnetic strips are provided for mounting of both thermometer and bottle sensor. Supplied with a Traceable® Certificate and AA battery for continuous, 1-year “always-on” monitoring. Replacement battery Cat. No. 1111.
