When buying a SHAW dew point sensor, you know that you’re buying into over 60 years of proven technical experience.

Dewpoint Sensor Picture

Manufacture: Shaw Moisture Meters
Model: Dewpoint Sensor

The aluminium oxide sensor, used for measuring trace moisture in dry compressed air and process gases is a great example of why you can always put your trust in Shaw Moisture Meters.

Construction of the aluminium oxide sensor is critical to the performance and reliability of systems and yet the construction varies from manufacturer to manufacturer. The methods used by SHAW are tried, tested and trusted, involving layering and treating high quality components in such a way to control sensor speed, sensitivity and base capacity.
