SDI-12 Sensor List

The Serial Digital Interface Protocol (SDI-12) is a set of rules that define exactly how a sensor communicates with a data logger. SDI-12 is endorsed by the world's most respected water monitoring agencies including the US Geological Survey and Water Surveys Canada. In addition to creating a 'smart sensor' by equipping it with a microprocessor, any SDI-12 sensor can be interfaced to any SDI-12 datalogger.

DTS-12 Turbidity Sensor The Digital DTS-12 features high accuracy, excellent thermal and long-term stability, and nearly linear response over three orders of magnitude. Effective in low water levels and sensitive to low levels of turbidity while still retaining a wide absolute range, the Digital DTS-12 is the result of four years of research, engineering development and product testing.
Solar Radiation Sensor The Solar Radiation sensor monitors any one of three forms of solar radiation. PAR-Photosynthetically Active Radiation. PYR-Pyronometer. PHO-Photometric Sensor.	Barometric Pressure Sensor The SDI Barometric Pressure Sensor is a highly accurate, solid state pressure transducer capable of operating between the elevations of -1200 and +13,000 feet.
Kipp&Zonen Solar Radiation Sensor The Kipp & Zonen secondary standard pyranometer is suitable for the measurement of solar irradiance on a plane surface.	SDI Expansion Box The SDI expansion box can be used to add additional SDI sensors to an FWS-12S datalogger
Float Gauge (Measures Depth) The float gauge is ideal for measuring water level where a stilling well exists or is easy to construct.	Water Quality Multi-Parameter Probe Measures conductivity and temperature. The probe can be used 200 feet below the water's surface or in as little as a few inches of water.
Submersible Pressure Transducer (Measures Depth) This submersible sensor has fast acting temperature compensation and has been specifically designed to provide repeatable precision depth measurements.	Autosampler A programmable liquid sampler designed to collect up to 24 separate water samples. Sampling can be activated by any parameter that is being measured at the site. !UPDATE!
SDI Sampler Interface SDI control interface for portable samplers.
