CS215-PWS Temperature and Relative Humidity Sensor

For this version of the CS215 Temperature and RH Probe, the cable has, instead of pigtails, a connector for attachment to the PWS100. Cable length is 1 meter. The CS215-PWS makes accurate, stable measurements of both temperature and relative humidity. The Sensirion element can be replaced in the field by the user, eliminating the downtime typically required for a sensor recalibration. The CS215-PWS should be housed in a 41303-5A 6-Plate Naturally-Aspirated Radiation Shield.

41303-5A Radiation Shield

The 41303-5A is a naturally aspirated 6-plate radiation shield. Its louvered construction allows air to pass freely through the shield thereby serving to keep the probe at or near ambient temperature. The shield's white color reflects solar radiation.
