The Traceable WD-37803-88 High-Accuracy RTD Refrigerator/Freezer Thermometer easily monitor temperature in liquids, baths, air/gas, incubators, refrigerators, or freezers. The WD-37803-88 keeps track of temperature conditions overnight or for any time period—minimum and maximum temperatures are stored until the memory is cleared.

Model 37803-88 is supplied with a special bottle probe specifically designed for refrigerator/freezer applications. The temperature sensor is enclosed in a bottle, which protects it from rapid temperature changes when refrigerator door is opened.

The 4-wire platinum probe insures linear response and high accuracy across the entire range. The built-in alarm provides an alert when temperature rises above or falls below a user defined set point, and is programmable in 1° increments. A visual and audible signal continues even if the temperature returns to non-alarm range until reset by the user. Probe is attached to a 10-ft (3 m) micro-cable that permits a doors to close on it; probe and cable are both submersible. Mount meter with included hook-and-loop strips, wall-mount slots, or use flip-open stand on benchtop.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving users both time and money by not having to calibrate separately.
