The CS210 Enclosure Humidity Sensor contains an Elan HM2000-series precision bulk polymer relative humidity sensor. It senses relative humidity levels inside of the 18997 enclosure. The desiccant should be exchanged when the sensor indicates an RH level of 40% or more inside of the enclosure.
The 31551 is a kit to allow stacking of components inside Campbell Scientific enclosures. The kit includes two leg brackets. It is used to raise a datalogger up and off the backplate so that wiring is easier or so that components can be stacked.
The 31143 is a hinged stack bracket that is designed to fit a CR1000 datalogger, CR6 datalogger, or multiplexter on either the top or underneath. The hinge enables access to the equipment underneath without disconnecting any wires (assuming that the wires are long enough).
The enclosure supply kit includes desiccant, a humidity indicator card, cable ties, wire tie tabs, putty for sealing the conduit, and screws and grommets for attaching peripherals to the enclosure backplate.
