Measurement Considerations
To measure moisture, the MS120 sensor emits and senses low-power
electro-magnetic signals. The displayed reading in percent is an average
of the moisture content measured over the entire sensor’s surface area
(40x40mm [1.6x1.6”]) and the maximum depth of penetration (20mm
[0.8”]). Moisture that is closer to the surface has a greater effect on the
displayed average than the moisture nearer to the maximum depth of
penetration.
Placing the sensor on a surface whose thickness is less than the maximum
depth of penetration may result in unreliable moisture readings; in these
cases, you can stack material on top of the measured surface to increase
the thickness.
The MS120
also produces audible tones and ‘moisture droplet’ display
icons to indicate moisture level. The audible tone rate and number of
droplets increase as the moisture level increases. The MS120 also
