Price Match Guarantee & Advice

The Extech 44550 is a dual LCD tester that can measure both relative humidity and temperature at the same time.

Shaped like a pen, the 44550 is comfortable to hold and requires the user to hold the sensor near to an application in order to measure the two available parameters. The tester can measure relative humidity from 10 to 85% and temperature levels from 14 to 122°F (-10 to 50ºC).

On the front of the tester are also a selection of buttons that can be used to switch between Celsius/Fahrenheit modes and to active MAX/MIN measurement modes.
