- Complete measurement system with data acquisition
  at two or more measurement-points by H2S-monitoring
- Calibration related to the concentration of sulphide in
  waste water
- High sensitivity (below 0.01 ppm)
- Suck of the gas sample by a transfer line
  (up to 50 m length and 10 m depth)
- Selective electrochemical sensors
- Low maintenance effort by automatic
  zero-point-compensation
- Long life-time of the sensor due to an intermittent gas
  path control
- Integrated rinsing steps in order to guarantee current
  samples for analysis
- Analogue input connections for various pumps
  and signals
- Potential free switching outputs (e.g. sewage pumps)
- Output signal (4-20mA) to control dosing pumps for
  water-treatment-chemicals in oder to send the
  signals to a customers’ process control system
- Direct data acquisition in the device for several months
- Data transmission via GPRS
