Stationary water quality monitoring with nitrate probe SPS-NO3 • Robust, low maintenance single parameter sonde (SPS) made of 1.4571 stainless steel for the measurement of nitrate (NO3- , NO3-N) • Slim design (0 48.3 mm) for observation wells starting from 3" diameter • High measuring accuracy, drift-free, only annual verification of the calibration needed • Available in different measuring ranges up to max. 0... 266 mg/L NO3- • Output: RS 485 (SHWP, Modbus RTU) for the connection with SEBA data logger

Nitrate probe SPS-NO3 The problem: increasing nitrate pollution in natural water resources Drinking water supply in Germany and many other countries is largely covered by groundwater resources. But groundwater is increasingly polluted with nitrate. One reason is the extensive practice of nitrogen fertilization in agriculture. In addition to mineral fertilizers, substrates such as liquid manure from livestock farms or biogas plants are used for the crops. Left-over nitrogen components, which aren’t degraded by plants at the soil layer usually percolate into groundwater as nitrate. Accordingly,...

The perfect, self-sufficient SEBA water quality station with SPS-NO3: The protective housing concept The robust aluminum protective housing „Alpha“ is impact-resistant, functional and offers sufficient space for a data logger, remote data transmission and self-sufficient energy supply. A tilting mechanism enables the operator simply to fold away the protective housing in order to easily pull-out the nitrate probe SPS-NO3 and other probes for maintenance or control purposes. The logger and data transmission concept The core of the SEBA water quality station is the low-power data logger UnilogCom....
