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

section at the front of this
manual.
•
When opening the shipping package, do not damage or cut the cable
jacket. If damage to the cable is suspected, consult a Campbell Scientific
application engineer.
•
Although rugged, the HC2S3 should be handled as a precision scientific
instrument.
•
Do not touch the sensor element.
•
Santoprene
®
rubber, which composes the black outer jacket of the HC2S3
cable, will support combustion in air. It is used because of its resistance to
temperature extremes, moisture, and UV degradation. It is rated as slow
burning when tested according to U.L. 94 H.B. and passes FMVSS302.
However, local fire codes may preclude its use inside buildings.
3. Initial Inspection
•
Check the packaging and contents of the shipment. If damage occurred
during transport, immediately file a claim with the carrier. Contact
Campbell Scientific to facilitate repair or replacement.
•
Check model information against the shipping documents to ensure the
expected products and the correct lengths of cable are received. Model
numbers are found on each product. On cables and cabled items, the model
number is usually found at the connection end of the cable. Report any
shortages immediately to Campbell Scientific.
