The UNI 2 is an electronic multipurpose meter for three measured values. It can be used with active electrodes for measuring structural moisture, air humidity, and temperature. Additionally, all structural moisture measuringelectrodes that are based on the resistance principle of measurement may be connected to the UNI 2 unit. Quick measurement of moisture in set building materials using the resistance-based and capacitive radio frequency measuring techniques. Temperature measurement precision is achieved by Pt100 measuring resistors connected. In 4-wire technology. Measurements 140 x 89 x 50 mm. Weight 230 g. Instruction manual in Finnish. Proof of calibration.
