Model HC2S3 Temperature and Relative
Humidity Probe
1. Introduction
The HC2S3 is a rugged, accurate temperature/RH probe that is ideal for long-
term, unattended applications. The probe uses a Rotronic’s IN1 capacitive
sensor to measure RH and a 100 ohm PRT to measure temperature. For
optimum results, the HC2S3 should be recalibrated annually.
Before using the HC2S3, please study

2. Cautionary Statements
•
Care should be taken when opening the shipping package to not damage or
cut the cable jacket. If damage to the cable is suspected, consult with a
Campbell Scientific applications engineer.
•
Although the HC2S3 is rugged, it should be handled as a precision
scientific instrument.
•
Do not touch the sensor element.
•
The black outer jacket of the cable is Santoprene® rubber. This
compound was chosen for its resistance to temperature extremes, moisture,
and UV degradation. However, this jacket will support combustion in air.
It is rated as slow burning when tested according to U.L. 94 H.B. and will
pass FMVSS302. Local fire codes may preclude its use inside buildings.
3. Initial Inspection
•
Upon receipt of the HC2S3, inspect the packaging and contents for
damage. File damage claims with the shipping company.
•
The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the correct product and cable length are received.
•
Refer to the Ships With list to ensure that parts are included (see Section
3.1). The HC2S3 probe and its calibration card are shipped in a small box,
with the box and PN 27731 Hex Plug attached to the cable.
