Wood Moisture

BL A plus

Ref.Nr. 30011200Multi
Capacitive and resistance measurement method (wood moisture) combined in one device

The possibilities offered by high-precision resistance-based measurement method and the non-destructive capacitive measuring method are now combined in one compact measuring instrument: the Hydromette BL A plus. It is perfectly suitable for determining the moisture content of sawn timber (up to 180 mm thick), chipboard and veneer. 

The Hydromette is equipped with a high-quality measuring amplifier and an OLED display. The new ResCap mode combines the reliability of the resistance-based measurement method with the easy handling of the capacitive measuring mode

The resistance-based measuring mode features a wood species selector for more than 300 species as well as a temperature compensation device, which is manually adjustable. 

The capacitive measuring method enables fast measurement, for it is not necessary to drive any electrodes into the wood. Wood species correction is available for more than 50 species. 

Limit values can be set freely. If a measured value crosses such a threshold, the meter will indicate this through a flashing LED.
