Model 109SS Temperature Probe

8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the

PC to datalogger connection is active, you can click Finish in Short Cut

and you will be prompted to send the program just created to the

datalogger.

9. If the sensor is connected to the datalogger, as shown in the wiring

diagram in step 6, check the output of the sensor in the datalogger support

software data display to make sure it is making reasonable measurements.

5. Overview

The 109SS is a rugged probe that accurately measures soil or water

temperature in a variety of applications. The sensor consists of a thermistor

encased in a stainless-steel sheath. This design protects the thermistor,

allowing the 109SS to be buried or submerged in harsh, corrosive

environments. It can be submerged in water to 45 m (150 ft) or 63 psi. See

Specifications for a complete list of compatible dataloggers.
