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. 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.

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.

Solid-state probe eliminates mercury contamination in refrigerators. Probe is sealed in a miniature bottle (1 x 2¹/₂ in.) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about contact with food or drinking water.

To assure accuracy an individually serial-numbered Traceable Certificate is provided from an 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. Supplied: Traceable Certificate, flip-open stand, wall mounting, Velcro, and magnetic strips. Replacement battery Cat. No. 350-20158.
