Technical Description

For this version of the 108 thermistor, the cable terminates in a connector rather than the standard pigtails. The connector can be attached to the ET107 Weather Station, ET106 Weather Station (retired), or MetData1 Weather Station (retired).

The 108-LC can be used to accurately measure the temperature of a variety of media, most commonly air, water, and soil. It consists of a thermistor encapsulated in a cylindrical aluminum housing. The 108-LC measures the range of -5° to +95°C; to measure the -35° to +50°C temperature range, see the 107-LC probe.

Soil Measurements
The 108-LC is suitable for shallow burial only. It should be placed horizontally at the desired measurement depth to avoid thermal conduction from the surface to the thermistor. Placement of the sensor 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.
