The HANNA® HYGROCHECK uses the advanced TFPC® sensing method to measure humidity and an integrated electronic circuit to perform all relative conversions. This method of Relative Humidity measurement assures a quick and accurate reading. With a complete measurement range of 10% to 90% RH and an accuracy of 3% across the entire range, HYGROCHECK is the most complete and versatile pocket-sized Hygrometer available!

Most hygrometers on the market today are too large or heavy to be carried around together with other instruments for on-the-spot testing. The pocket-sized HYGROCHECK is only 180 x 30 x 15 mm (7.1 x 1.2 x 0.6") and weighs just 62 grams (2.2 oz.). This compact, rugged unit will slip right into your pocket and can be carried anywhere!

The housing is constructed of durable ABS material and the LCD is protected beneath a transparent plastic cover. The LCD displays the RH reading digits that can be read from any angle. Also, a vented cap protects the sensor while allowing maximum airflow for rapid response.

Unlike a ordinary hygrometer, HYGROCHECK performs all relative conversions electronically.
