The World's Best Instream Turbidity Sensor™
Stability and accuracy unlike anything else.
The DTS-12 is the first sensor to make instream turbidity monitoring practical. The value of continuously monitoring turbidity has long been recognized, but it’s always been difficult, inaccurate, expensive, labor-intensive, and therefore often dismissed as too impractical. The DTS-12 is different—we state with confidence that it’s the “world’s best” because its unique design delivers extremely low maintenance (just clean and re-calibrate once a year) and extremely high accuracy over the full measureable range of 0-1,600NTU. Unlike multisondes, the DTS-12 does one task, but does it exceptionally well (it’s also less expensive and simpler to deploy).

Connect directly to an automatic water sampler.
- Optional connector allows connecting the DTS-12 directly to an ISCO automatic pump water sampler.
- Allows simple water sample collection by triggering the autosampler when turbidity reaches a specific threshold.
- Used for complex water sample collection (such as turbidity threshold sampling" which strategically collects only the "right" samples) that can permit true correlation to accurately determine suspended sediment loads, ourSedEvent system is a turn-key system that makes suspended sediment concentration (SSC) determination realistic and practical.
The digital advantage.
- Long cable runs are possible without signal degradation and noise common with analog sensors.
- Calibration coefficients stored in sensor eliminating reprogramming of datalogger when changing sensors.
- Compatible with all dataloggers supporting the SDI-12 protocol.
Set it and forget it. For up to 12 months.
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.
- 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 wiper provides effective long-term cleaning performance. Non-abrasive silicone wiper blade prevents optical face abrasion.
- Integrated thermal compensation provides very high thermal stability of light source and electronics.
