Non-destructive measurement: electromagnetic wave sensing technology has penetration ability and deeper measurement depth. It can read the reading instantly through simple contact without damaging the surface of the object Digital display: widescreen digital backlight display can clearly display the measurement reading even in low-light environment. The instrument design adopts low-power large-scale integrated circuits and liquid crystal display technology, which consumes low power Fast measurement: fast measurement speed, which can replace the traditional oven method, shorten the moisture measurement time, and read the measurement value in 1 second, which greatly saves the precious time of the inspector Corresponding detection: different codes are selected according to different species to greatly improve the accuracy of measurement Easy to carry: small size, light weight, strong anti-interference performance, can be carried on site for rapid detection
