The four-alarm thermometer has two temperature sensors—a built-in air sensor and an independent external probe sensor with 3-1/2 foot long cable. Use the external probe to monitor temperatures of liquids, air/gas, and semisolids. Multiline LCD features 1-1/8"H digits, making it easily visible from a distance.

Set alarm configurations for up to four conditions: temperature above a setting, below a setting, between two settings, or outside two settings. A green or red light will blink, and an audible alarm will sound when one of these conditions is detected. The alarm will sound every minute for 5 seconds until the temperature returns to a nonalarm condition or until the alarm is turned off.

Traceable® Products come with an individually numbered Traceable® Certificate provided with each unit, assuring accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. The certificate indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. Every Traceable® product undergoes an intense vetting process before it can carry the Traceable name, saving you both time and money by eliminating the need for separate calibration.

Guaranteed to have at least one year of calibration remaining on certificate.
