The Unidata 6537 Starflow QSD SDI-12 and Modbus Instrument has a 4 electrode electro conductivity instrument (EC) included for measuring the quality of the water. Water quality is measured on an ongoing basis and this parameter can be recorded along with velocity and depth to better analyse the nature of the water in open channels and pipes. Conductivity is a very important water quality measure and any spike on the conductivity is a strong indicator of a pollution event.
Conductivity (6537 Only): 0-200,000uS/cm Typically ±1% of measurement, returned either as 16-bit value (0 65535uS/cm) or 32-bit value (0-262,143uS/cm)
Compensation Conductivity (6537 Only): 25°C default / set using configuration tools
Cable: 15 metre, 6 way
Cable Options: User specified up to 50 metres
