Extech MO257
无探针式湿度计
Take non-invasive, pinless moisture measurements on wood and building materials with Extech's MO257 Moisture Meter. Easy-to-operate with automatic calibration, this meter has a ball moisture sensor that provides smooth gliding on hard or delicate surfaces. A large backlit triple LCD displays moisture reading and Max and Min readings; user can also adjust two alarm levels to display a visual alert (flashing “RISK” or “WET” indicators) plus a beeper alert. The MO257 is a must-have tool for analyzing the after-effects of water leakage behind walls and in ceilings and also measuring moisture content on a non-flat surface.
非侵入性测量的相对无探针式水分测量读数为 0.0–100.0（0.1 分辨率），灵敏度范围为表面以下 20–40 mm
两个可调节的警报等级，配有声光报警器，仪表开机后，可自动实施校准（在干燥空气中）
建筑修复项目和应用的理想选择，在这类项目和应用中对地板和瓷砖上的水分检测以及地毯下的水分检测至关重要
