Relative Humidity sensor
This optional capacitive relative humidity sensor is compact and easy to
use. It can be easily installed in a self-aspirating radiation shield for
protection from the sun and rain. This sensor offers long-term stability
with minimal drift. Because the sensor is a capacitive device, it will not be
affected by surface contamination in unclean environments. Since the
sensor element is socketed and laser trimmed it can be easily replaced
in the field without any additional calibration. The relative humidity sensor
comes with a standard 50-foot cable and a quick disconnect connector.
