More About This Item

This professional thermohygrometer provides accurate and reliable readings in an ergonomic handheld design. Double-molded heavy-duty housing provides superior protection and is ideal for tough applications. Use it in laboratories, cleanrooms, warehouses, factories, and storage areas—anywhere you need to check the humidity and temperature levels.

View humidity, dew point, wet bulb, and temperature readings on the large backlit LCD. The meter can also measure in absolute humidity grains per cubic feet or per cubic meters. Other features include Min/Max and Hold functions, user-selectable temperature readout in °F or °C, integrated humidity and temperature (NTC thermistor) sensor, and auto power-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.
