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 unit will continue to alarm until acknowledged on the device, even if the alarming parameter returns to within range. View the minimum, maximum, and current humidity or temperature readings on the large-digit, triple display; switch between measured values with the press of a button.

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.
