Overview
The 108-LC is a version of the 108 that has a cable terminated in a connector rather than the standard pigtails. The connector can be attached to the CS110 lightning meter or to the ET107, ET106, or MetData1 weather stations.
The 108-L is a rugged, accurate probe that measures temperature of air, soil, or water from -5° to +95°C. Designed for durability and ease of installation/removal, the 108-L easily interfaces with most Campbell Scientific dataloggers.

Detailed 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.

Compatibility
The cable of the 108-LC provides a connector that attaches to the ET107 Weather Station, ET106 Weather Station (retired), or MetData1 Weather Station (retired). The ET107 Weather Station has an on-board CR1000M module. Both the MetData1 Weather Station and ET106 Weather Station have an on-board CR10X module.
Solar Radiation Shields
When exposed to sunlight, the 108 must be housed in a radiation shield. It is typically housed in a 41303-5A 6-plate naturally aspireated shield. It may also be housed in a 41003-5 10-plate shield if a 41322 Adapter Plate is used.
Multiplexers
To measure large numbers of probes, the AM16/32B multiplexer is recommended.
