The Traceable 20250-21 Professional Thermohygrometer provides accurate and reliable readings in an ergonomic handheld design. Ideal for use in laboratories, cleanrooms, warehouses, factories, and storage areas.

Double-molded heavy-duty housing provides superior protection and is ideal for tough applications. The 20250-21 provides measurements in humidity, dew point, wet bulb, and temperature. The meter can also measure in absolute humidity grains per cubic feet or per cubic meters. View measurements in low light areas with large triple digit backlit display. Meters feature 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 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 both time and money by not having to calibrate separately.
