The 108 is a rugged, accurate probe that measures the temperature of the air, soil, or water from -5° to +95°C. It easily interfaces with most Campbell Scientific dataloggers and can be used in a variety of applications.
The 108 consists of a thermistor encapsulated in an epoxy-filled aluminium housing. The housing protects the thermistor. allowing you to bury the probe in soil or submerge it in water.
