HMP155A Temperature and Relative Humidity Probe 1. Introduction The HMP155A probe monitors relative humidity (RH) for the range of 0 to 100% RH and temperature for the range of -80° to +60°C. It can provide reliable measurements for a wide range of applications, as part of a weather station system or as a single instrument. All Campbell Scientific dataloggers are compatible. Before using the HMP155A, please study • Section 2, Cautionary Statements • Section 3, Initial Inspection • Section 4, Quickstart More details are available in the remaining sections. 2. Cautionary Statements • READ AND UNDERSTAND the Precautions section at the front of this manual. • 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 a Campbell Scientific application engineer. • Although the HMP155A 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 HMP155A, 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). 1

Cautionary Statements
•
READ AND UNDERSTAND the
Precautions
section at the front of this
manual.
•
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 a
Campbell Scientific application engineer.
•
Although the HMP155A is rugged, it should be handled as a precision
scientific instrument.
