Soil & Water Temperature Sensor


  • Soil temperature
  • Streams
  • Surface water
  • Stilling wells
  • Dams
  • Aquaculture tanks

Digital in every water area

The FTS DigiTemp 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 a fully digital sensor, and is compatible with any SDI-12 compliant datalogger, like the Ser[LOG].

  • No complex wiring to set up · just plug it in and forget it. 
  • 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.

rain[e] · Weighing precipitation sensorrain[e] Weighing precipitation sensor

rain[e] is a new type of weighing precipitation sensor: Highest resolution combined with the most compact design.

The unique self-emptying collection system enables the measurement of every single drop with the high resolution of 0.001 mm/m2. Full functionality all year around without antifreeze fluid makes the rain[e] very environmentally friendly.

rain[e] is easy to lift, transport, install and maintain. The small packing volume and the low weight ensure minimum logistical effort.

The rain[e] series is compatible with OTT and Campbell Scientific data loggers and ideal for setup and expansion of rainfall measurement networks.

  • Amazing resolution and accuracy
  • Checking of sensors with tipping bucket and other weighing systems
  • Compact and robust construction with a very low weight
  • All-metal housing, weatherproof and durable
  • Best connectivity by several interfaces
  • Easy to install and maintain

Also with Modbus or customised protocols realisable!
