On-Site SF Gas Analysis - MBW Calibration AG

, HF etc. To meet specification, dew point sensors depend on accurate calibration both during production, and use. Calibration drift can be significant, so regular calibration is essential to maintain reliable results. Chilled mirror hygrometers are based on the physical principal of condensation formation on a temperature controlled surface.

A Moisture Content Standard provides one or more additional checkpoints, thus assuring the professional that the moisture meter is calibrated across the board. For example, the hay moisture meter F2000 has a built-in calibration check at 12%. However, a Moisture Content Standard would also offer checkpoints at 16% and 22%, providing a greater degree of confidence. For the BD 2100, the Moisture Content Standard would verify the meter’s built-in check at 12% and offer an additional

Moisture Meter Calibration

How To Calibrate A Moisture Meter . You need to select a standard against which you will measure your readings. Depending upon the species of wood you may have different standards, but for this article we will say 20% as the standard for calibration. Some meters will default to a preset percentage when they are turned on so you will have to change that point. Next run a calibration test on your meter.
