Description:

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 are tried, tested and trusted and involve layering and treating high quality components in such a way that you can control sensor speed, sensitivity and base capacity.

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.


P (Purple): -100 °C to 0 °C (-148 °F to +32 °F) DP, 0 – 6,000 ppm

S (Silver): -100 °C to -20 °C (-148 °F to -4 °F) DP, 0 – 1,000 ppm

G (Grey): -80 °C to 0 °C (-112 °F to +32 °F) DP, 0 – 6,000 ppm

R (Red): -80 °C to -20 °C (-112 °F to -4 °F) DP, 0 – 1,000 ppm

B (Blue): -80 °C to +20 °C (-112 °F to +68 °F) DP, 0 – 23,000 ppm

Features:
