Proster PST199 Pinless Moisture Meter
Introduction
Congratulations on your purchase of this pinless Moisture Meter. Please read
this user guide carefully and thoroughly before using the instrument.
This instrument is designed for use in woodworking, water damage restoration,
building construction and home renovation. For example:
- Checking for moisture on or below the surface of carpets and subflooring
- Measuring the moisture content of wood, drywall, masonry or concrete before painting, wallpapering, sealing or treating
- Locating water leaks above ceilings, below floors or behind walls
- Selecting dry lumber
The meter is a pinless instrument that can detect moisture up to 3/4 in. (19mm) below the surface of the following materials: wallboard, masonry, hardwood and softwood. It infers the level of moisture from the material’s capacitance, which the meter measures by gauging its effect on an electric field that the meter generates each lime ii is powered on.
“MODE” button on the front of the instrument provide a convenient way to switch among the four materials. The name of the material selected appears on the LCD. Over the LCD is a bank of colored LEDs that roughly mirrors the digital reading above it in bar graph format, with green indicating “dry”, red indicating “wet”, and yellow indicating an intermediate moisture level. An audible out-of-range alarm (beeper) sounds whenever wood is tested and found to have a moisture content above 16%, or when drywall or masonry is found to be more than 53% wet.
To extend battery life, the instrument automatically powers off after five minutes of inactivity. The instrument is powered by a “9V battery” included in the pack.

Operation instructions
To power on the meter, press the “ ” button (To power off the meter, follow
the same instruction.)
To measure the moisture level of wall, masonry, hardwood or softwood, press
the “MODE” button until the name of that material appears on the LCD. Then
scan the material by gently pressing the inductive sensing area on the back of
the meter against the material. The LCD will read out the material’s moisture
content.
Simultaneously, one or more bar graph LEDs will illuminate to place the material’s moisture level within a spectrum bounded by “dry” and “wet”.
To hold a reading, press the “HOLD” button briefly. The display will show the held value, along with a lock icon. If the reading is above the alarm limit for that material, pressing the “HOLD” button will silence the beeper.
Measurement tips
For maximum accuracy, press the sensing area against a flat area of the material.
Ideally, the material should be at least 3/4 in. thick. That is the meter’s maximum measurement depth and the thickness it is calibrated for. If your sample is too thin, the meter will measure material beneath it as well and produce an inaccurate reading. One way to compensate for thin samples is to stack them.
The sample’s length and width should be at least as large as the dimensions of the sensing area: 1.6 X 1.6 in. (40 X 40mm)
Measurements of wood are skewed by two variables: ambient humidity and the density of the wood species. The best way to compensate for the effect of these variables is to develop your own moisture level curves, based on your experience working with different species of wood on a day-to-day basis.
Note: This instrument is a high-resistance instrument. All parts must have good insulation. During storage and use, attention must be paid to moisture and dust prevention. Keep the instrument dry and clean to ensure the accuracy of the measurement. When the instrument is not in use, store the instrument in a stable, dust-free environment out of direct sunlight. Remove the battery from the instrument if it is to be stored for periods of more than one month, or when the low battery power symbol appears on the display.
Battery replacement
When the low battery icon appears on the display, replace the battery as soon as practical.
- Remove the rear battery compartment cover.
- Replace 1x”9V” batteries.
- Cover the compartment door.
