Additional Compatibility Information
Data Logger Considerations
Programming
The instruction set for our CR200(X)-series, CR800-series, CR1000, and CR3000 dataloggers contains the Therm109 instruction for measuring the 109SS probe. Programming is more complicated for other data loggers because they must use generic measurement instructions.
Installation Considerations
Soil Temperature
The 109SS is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.
Water Temperature
The sensor can be submerged to 46 m (150 ft) or 63 psi. Please note that the 109SS is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.
