The CS215-PWS is a temperature and relative humidity probe with a special connector on the cable for attaching to a PWS100. It uses a Swiss-made digital humidity and temperature element that makes accurate and stable measurements. The CS215-PWS outputs an SDI-12 signal measurable by most Campbell Scientific data loggers.
Read MoreFor this version of the CS215 Temperature and RH Probe, the cable has, instead of pigtails, a connector for attachment to the PWS100.
The CS215 uses the Sensirion SHT75, a combined relative humidity and temperature element, to provide accurate, stable measurements. The Sensirion SHT75 element is field-replaceable, eliminating the downtime typically required for the recalibration process. The CS215 outputs an SDI-12 signal that's measurable by many Campbell Scientific data loggers.
The CS215 should be housed in a solar radiation shield—typically the 41303-5A. The 41303-5A 6-plate naturally aspirated shield attaches to a mast, crossarm, or tower leg.
