Unique, self-cleaning

The marine-capable DTS-12 is the World’s Best Instream Turbidity Sensor.

Using true Nephelometric geometry, along with a durable optical face and angled head that sheds bubbles, it provides extremely clean, highly precise data with repeatable, long-term accuracy. The DTS-12 exhibits less than 2 % annual optical drift, providing an incredible 12-month recalibration interval. The unique self-cleaning wiper minimizes bio- fouling. These features can typically save 11 site visits per year.

Set it and forget it. Accurate readings for up to 12 months.

  • The DTS-12 is the first turbidity sensor to use a laser diode light source, a coherent, narrow, near-infrared spectral beam that provides a constant intensity with virtually no degradation over time.
  • Unique, self-cleaning, bi-directional design utilizes a back- and-forth motion and two cavities in the face of the sensor that scrape away any fouling twice each time the wiper is activated.
  • Non-abrasive silicone wiper blade prevents optical face abrasion and cannot be impregnated with sediment or bio-fouling.
  • Integrated thermal compensation provides very high thermal stability of light source and electronics.

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!
