The Orion 910 uses electromagnetic wave technology to take non-damaging, pinless moisture readings in wood from the surface down to 0.75˝ in depth. IntelliSense™ Technology ensures accurate determination of moisture content deeper in the wood while minimizing the effect of surface moisture on readings. Measure practically any softwood or hardwood species in the world as well as non-solid wood products such as plywood, OSB, or MDF and many bamboo flooring products. Additional features include calibration in as little as 30 seconds, a HOLD function, auto shutdown, and an audible alarm for high moisture content levels. Includes meter, paired on-demand calibrator, rubber protective boot, 9V battery, instruction manual, and foam-lined ABS plastic carrying case. 7-Year warranty from the manufacturer.
