MS245
Pin/Pinless Moisture Meter
Introduction
- The tester professionally measuring moisture in the material using probe and inductive sensors.
- The two modes can be switched at will, material moisture values can be displayed in real-time.
- Two materials can be measured in probe mode: wood and construction.
- In induction mode, 10 materials can be measured: Dry wall, Masonry, Hardwood, Softwood, Hard gypsum floor (Wt%), Hard gypsum floor (CM%), Cement (Wt%), Cement (CM%), Concrete, Gypsum plaster.
- Can be simple button operation and comfortable feel, so that users can use this instrument more easily and quickly to measure.
Note: CM% is carb method and Wt% is water weight method.

Operation
5-1.Startup & Shutdown
- Press the ON/OFF Button to start on, press the ON/OFF Button to shut down.
- The hand shall be kept as far as possible from the humidity board.
5-2.EXT/REL Mode Switch
- Short the EXT/REL Button enables probe and inductive mode switching.
- The symbol of the EXT appears when switched to the probe type.
- When switched to the induction, the REL symbol appears.
- Probe shall be pressed into the material whenever possible.
- Induction measurement shall be as flat as far as possible.
5-3.Material Type Switch
- When switched to the probe type, 2 materials can be measured for wood and building, with numbers corresponding to the numbers 0-1.
- When press the MODE Button briefly, the material number add 1,when numbered to 1, press the MODE Button short and change the number to 0.
- When switching to the induction type, 10 materials can be measured, with the number corresponding to the number 0-9.
- When short press of the MODE Button, the material number adds 1, when the number reaches 9, press the MODE Button short, and the number changes to 0.
5-4.Automatic Shutdown Function
- When the automatic shutdown function is off, press the MODE Button for the automatic shutdown function on.
- When the automatic shutdown function is turned on, long press the MODE Button, and the automatic shutdown function turns off.
