98767-54 Traceable Ultra™ Refrigerator/Freezer Thermometer with Calibration; 1 Bottle Probe by Digi-Sense

Accurately monitor temperatures in refrigerators, freezers, water baths, and incubators. Thermometers have accuracy of ±0.5°C (-30 to 50°C). Built-in audible and visual alarms activate when temperature rises or falls below the alarm set point, and is programmable in 0.1° increments.

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 you both time and money by not having to calibrate separately.

Thermometer comes with a bottle probe filled with nontoxic glycol solution, eliminating the possibility of contamination from mercury. Solution is GRAS (generally recognized as safe) by the FDA. The solution filled bottle simulates the temperature of other stored liquids and eliminates the rapid temperature fluctuation caused by opening the refrigerator/freezer door.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory|Triple display simultaneously shows MIN/MAX and current temperature|10-ft microcable allows refrigerator/freezer doors to close on it
• Temperature-buffered glycol bottle probe mimics solution

Includes

glass bottle probe with 10-ft cable, flip-open stand, hook-and-loop strips, magnetic strips, wall mount, batteries, and NIST-traceable calibration certificate with data.
