Model 108 Temperature Probe 

1.  Introduction 

The 108 Temperature Probe uses a thermistor to measure temperature in air, 

soil, and water. It is compatible with all CRBasic dataloggers except the 

CR200(X) and CR9000(X). See Section 

6

Specifications

 

(p. 4)

, for a list of 

compatible CRBasic dataloggers. 

For Edlog datalogger support, check the availability of an older manual at 

www.campbellsci.com/old-manuals

, or contact Campbell Scientific for 

assistance. 

2.  Precautions 

READ AND UNDERSTAND the 

Safety

 section at the front of this manual.  

Santoprene

®

 rubber, which composes the black outer jacket of the 108 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.  

4.  QuickStart 

A video that describes programming using 

Short Cut

 is available at: 

www.campbellsci.com/videos/cr1000x-datalogger-getting-started-program-

part-3. 

Short Cut 

is an easy way to program your datalogger to measure the 

108 probe and assign datalogger wiring terminals. 

Short Cut

 is available as a 

download on 

www.campbellsci.com

. It is included in installations of 

LoggerNet

PC200W

PC400

, or 

RTDAQ
