Humitest measures moisture content
May 19, 2011 – An on-site moisture meter
can save time and money. To be able to measure moisture content precisely,
three parameters are significant: the representativeness of the sample, the
reliability of the instrument used for measuring, and procedural compliance by
instrument operator. Oven drying is the reference method to measure the
moisture content of wood chips, but it is costly and time consuming.
Moisture meters for solid biomass marketed
by Domosystem are designed for instant and reliable measurements on site and
are calibrated according to the oven-dry method.
The Humitest for wood chips, calibrated
for several types of wood chips, completes the range of moisture meters that
allow the measurement of biomass moisture content. The Humitest for biomass and
for biomass plus, launched in 2009, are used by forest cooperatives and other
wood producers as well as heating operators and local authorities.
The new Humitest is aimed at wood-chip
buyers whose priority is a simple and quick moisture measurement. Fitted with a
1 m long probe, the Humitest for wood chips allows the measurement of moisture
content and temperature in the core of a heap of wood chips. The user selects
one calibration from the three available calibrations: P16 and P45 forest wood
chips, industrial, or sawmill wood chips. The user inserts the probe so that
the electrodes at the end of the probe are in close contact with the measured
wood chips. Moisture content and temperature readings are displayed instantly.
