108-L

Temperature Sensor

The 108 is a general purpose temperature sensor that can be used to accurately measure the temperature of a variety of media, most commonly air, water, and soil.

The 108 consists of a thermistor encapsulated in a cylindrical aluminum housing. The probe measures temperature from -5° to +95°C and is designed for durability and ease of installation/removal.


Features

  • Sensor measures air, soil, or water temperature
  • Incorporates a thermistor as the active element
  • Recommended for -5° to +95°C temperature range
  • Naturally aspirated radiation shield recommended when sensor is exposed to sunlight
