Model EE181 Temperature and Relative
Humidity Probe
1. Introduction
The EE181 is a rugged, accurate temperature and relative humidity probe that
is ideal for long-term, unattended applications in all climates. The probe uses
an E+E Elektronik ® capacitive RH element with a proprietary coating to
measure relative humidity and a 1000 Ω PRT to measure temperature. For
optimum results, the EE181 should be recalibrated annually.

2. Precautions
•
READ AND UNDERSTAND the Safety 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
representative.
• Although rugged, the EE181 should be handled as a precision scientific
instrument.
•
Do not touch the sensor element.
•
Santoprene
®
rubber, which composes the black outer jacket of the EE181
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.
• Refer to Section 3.1 , Ships With
