Technical Information

The unique SHAW AutoCal feature and effective desiccant dry-down technology give accurate measurement of trace moisture in process gases and dry compressed air. Built with meticulous attention to detail and of the highest quality materials. Shaw Moisture Meters dewpoint instruments are suitable for a wide variety of applications.

AutoCal (automatic calibration) is one of the most important and unique features of the SHAW system for measurement of trace moisture. Designed and precisely manufactured to saturate with water vapour, the SHAW dewpoint sensor gives no further increase in response when it reaches its maximum moisture level. Perform AutoCal in-situ without special equipment, extensive training or skilled personnel, reducing downtime, minimising calibration costs and gaining immediate verification of the system… (read more)

Keeping the dewpoint sensor dry between tests ensures that the instrument is always ready to carry out rapid spot checks of trace moisture in gases and compressed air. The sensor is prevented from coming into contact with ambient conditions. The unique design of the desiccant head assembly surrounds the dewpoint sensor with desiccant before lifting the head for sampling. This ensures the sensor is always operated from dry to wet for increased speed of response… (read more)

To help with dewpoint calculations, Shaw Moisture Meters offer two types of dewpoint calculator. Choose from the manual or online version to calculate accurate dew point results of trace moisture in dry compressed air and process gases. View your calculations or convert to your chosen dew point unit. Equivalent measurements displayed in °C, °F ppm(V), ppm(w), g/m³ and lb/MMSCF. Please note: All conversions from the manual dewpoint calculator are based on ideal gas behaviour.
