The meter warns you of environmental conditions that are out of a desired range with an audible alarm and bright red LED indicator. Features include a super-large, triple display for relative humidity, temperature, and dew point; min/max with reset function; and switchable °F/°C units.

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.
