Model 1812 Laboratory Moisture Calibrator

To calibrate other moisture monitors, or as a stand-alone moisture monitor.

The operating principle of the calibrator is to generate a continuous flow of low level (ppm) water vapour in a nitrogen carrier gas to be used to calibrate other moisture monitors. This device can also be used as a moisture analyser if required.

Dry nitrogen is fed through a bubbler, the flow rate being adjusted to deliver a constant flow of known ppm moisture in the stream. An internal analyser measures the moisture content and the instrument delivers up to 2 l/min moisture in nitrogen to an external moisture monitor which in turn can be calibrated or validated.

Suitable for calibrating or validating any moisture monitor in the 0-1,000 ppm by volume range.
