DigiTemp Water Temperature

DigiTemp Water Temperature Sensor

The FTS DigiTemp submersible water temperature sensor is a rugged SDI-12 sensor for measuring the temperature of soil, water or other liquids with scientific- grade accuracy and long-term reliability. It makes adding automatic temperature monitoring to existing stations incredibly easy and cost-effective.

DigiTemp is small enough to easily deploy through standard 1” (2.5 cm) PVC conduit with 8” (20.3 cm) factory bend corners.

DigiTemp is a fully digital sensor, using the SDI-12 protocol, and is compatible with any SDI-12 compliant datalogger, like the Axiom.

Just plug it in and forget it.

  • No complex wiring to set up.
  • Because it is a linear sensor, no need to program coefficients.
  • Flexible strain relief cable is durable, watertight, and UV-resistant. Supports cable length up to 152 m (500′) with no impact on performance.
  • Strong molded end loop for attaching weights or other mechanism for helping to fish through conduit.
