  • Model 20250-11 can also measure absolute humidity and has unique side button controls for easy one-handed operation
A digital hygrometer, also known as thermohygrometer, measures and simultaneously displays temperature and humidity measurements. Davis Instruments offers a digital hygrometer among the many other meters it features in its online and print catalog. Meters are available with integral probes or remote probes, depending on your application. For measurements that are convenient and easy-to-reach, select a meter with an integral probe that allows one-handed operation. When measurements are necessary in hard-to reach areas, meters with remote probes provide access, as well as, easy display readability. Select from thermohygrometers that offer features such as data hold, min/max, data logging, infrared temperature measurements, RS232 output, printing capabilities, selectable temperature units and many other features. Humidity sensors provide high level of accuracy and ability to be calibrated for continued accuracy and stability. Sensor calibration is available through our in-house calibration lab, InnoCal, or available calibration salts. Thermohygrometers are ideal for use in HVAC, IAQ and other environmental industries, and industrial applications. If you have questions about a digital hygrometer contact a Davis Application Specialist today. The Digi-Sense handheld thermohygrometers provide reliable and accurate readings in an economical and ergonomic design. Ideal for use in cleanrooms, HVAC, laboratories, IAQ, warehouses, factories and storage areas. Additonaly, 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.

What's Included:
Carrying case, three AAA batteries, and NIST-traceable calibration report with data supplied by InnoCal. Model 20250-12 also includes a type K flexible probe
