KPM Aqua-Boy Electronic Timber Moisture Meter
Unit in perfect condition, measurement range 5 to 28%.
Leather case and hammer electrode included.
AQUA-BOY Moisture Meters are designed for easy portability, fast operation with instantaneous indication and universal use.
The AQUA-BOY meter is housed in a robust case, shaped to protect the large dial and controls. Power is supplied to the AQUA-BOY by a 9 V battery.
The measuring principle of the AQUA BOY is based on the electrical conductivity of the material which always bears a fixed relation to the moisture. All changes in resistance inside the measuring ranges of interest are sufficiently pronounced to ensure a high degree of accuracy for the readings obtained with the AQUA-BOY. The electrical indicating accuracy of the AQUA-BOY is +/- 0.1% while the reproducibility is +/- 0.2 % referred of the absolute readings on the meter dial.
