Dew you get the point?

Qrometric Ltd, a leading provider of precision calibration and measurement instruments, has introduced the FPG calibrator that for the first time enables on-site calibration of dewpoint and moisture instruments, including devices used in drying applications.

FPG requires no external gas supplies and uses a primary technique of humidity generation based on temperature measurement and control. It is compact and transportable so can be deployed on-site for in-situ test and calibration. The FPG generates the moisture condition in the test loop and is also calibration reference with traceability through ISO17025 calibration.

FPG was developed to be compatible with all types of dew point and moisture devices. The front panel calibration manifold has user configurable probe adapters to suit all types of dew point sensors. A sample loop is also included to connect with any type of moisture analyser using industry standard fittings, and the FPG includes a user variable speed sample pump for flow control, flow and pressure measurement.

FPG test and calibration range is from -100˚C frost point to +10˚C dew point (0.01 to 1200 ppmv) so it is suitable for all types of instruments used in drying processes. By optimising moisture measurements by calibration, dryer control is to more accurate values, avoiding over or under drying, which has a positive effect on efficiency and product quality.
