107-L Temperature Probe

ClimateMeteorological Station & Sensors

Th e 107 and 108 are rugged, accurate probes that measure air, soil, and water temperature in a variety of applications. Th ese probes consist of a thermistor encapsulated in an epoxy-fi lled aluminum housing. Th e housing protects the thermistor allowing the probes to be buried or submerged. Th e 107 measures from -35° to +50°C, the 108 from -5° to +95°C.
