108 Hitastigsnemi

The 108 is a rugged, accurate probe that measures temperature of air, soil, or water from -5° to +95°C. It easily interfaces with most Campbell Scientific data loggers and can be used in a variety of applications.

The 108 consists of a thermistor encapsulated in an epoxy-filled aluminum housing. The housing protects the thermistor. allowing you to bury the probe in soil or submerge it in water.

Benefits and Features

  • Versatile product—measures air, soil, or water temperature
  • Easy to install or remove
