& 9632;DM200W wood moisture meter detector adopts high frequency principle, digital display, sensor and host are integrated as one, equipped with ten gears for measuring various wood materials. The moisture meter has a high-precision measuring instrument, small size and light weight, which is convenient for field testing. The ideal instrument for detecting water during production in the wood industry.                 The working principle of DM200W wood moisture meter & 9632;This instrument adopts the principle of high frequency on the basis of introducing the most advanced technology from abroad. In other words, there is a fixed frequency inside the device. Once carried by the moisture of the detected object, the frequency of passing through the sensor will vary. The difference between the frequencies will be shown in a later figure converted by a current-to-frequency converter.                                                     & 9632;Its integrative design convenient to carry outside for testing.  & 9632;Digital display with back light gives exact and clearly reading although you stay at the somber conditions.  & 9632;It is small in size, light in weight ,easy to carry out for fieldwork if needed.  & 9632;Manual off at any time .Auto power off after 5 minutes from last operation.
