These thermohygrometers with alarm are perfect for monitoring critical environments during the day, overnight, and weekends. Alarms sound when humidity or temperature conditions rise above or fall below programmed set points.
The large-digit, triple display shows the MIN, MAX, and current humidity or temperature readings—switch between measured values with the press of a button. External sensor model 98766-85 features a 7-ft (2.1 m) long cable for monitoring in hoods, refrigerators, freezers, or other remote locations. Model 98766-48 has an integrated ambient sensor for obtaining readings where the unit is placed. Choose the model that suits your application needs!
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.
