Dewpoint Sensor

When buying a SHAW dewpoint sensor, you know that you’re buying into over 60 years of proven technical experience. The aluminium oxide sensor, used for measuring trace moisture in air and 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. Unlike other manufacturers, Shaw Moisture Meters has the capability to manufacture the sensor’s base layer with a level of precision that ensures a stable, reliable and drift free dewpoint sensor. Plus the continuous research and development programme has enabled the manufacture of uniform and water vapour specific pores for a rapid and predictable response. The overall measurement range covered by the sensor is –100 °C to +20 °C (-148 °F to +68 °F) dewpoint, which corresponds to 0.001 ppm to 0.2 percent by volume.
