37101-00 Traceable® Thermohygrometer with Minimum/Maximum Function and Calibration by Digi-Sense

Thermohygrometer displays temperature compensated relative humidity in % RH and temperature in °F or °C. Stores minimum and maximum RH and temperature readings - just press the front-panel MIN and MAX buttons to read stored values. Press the RESET button to continue displaying current RH and temperature conditions. Large LCD also indicates "comfort" ''wet'', or ''dry'' condition. Thermohygrometer features an integral stand for easy desktop viewing and a wall mounting bracket.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
