More About this Item

The Digi-Sense handheld thermohygrometers provide accurate and reliable readings in an ergonomic design. Ideal for use in HVAC, IAQ, laboratories, cleanrooms, warehouses, factories and storage areas. Plus the NIST-traceable precalibration means you get reliable measurements right out of the box, saving you time and money!

Large backlit LCD displays humidity, dew point, wet bulb, and temperature readings. 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.

Model 20250-12 offers an external thermocouple (T/C) type K input and dry bulb measurement. In addition, target superheat mode (TSH) and target evaporator exit temperature (TEET) calculations provide more accurate balancing of airflow systems, making it ideal for the HVAC and IAQ industries.
