Sample conditions:
Temperature: 0 to 50 °C
pH: 3 to 9 pH
Flow: 1 to 4 l/min, for pure water or municipal water application.
5 to 10 l/min, for raw water or sea water application.
10 to 20 l/min, for secondary sewage treatment application.
Pressure: 20 to 500 kPa
Electrodes:
Indicator electrode: Rotating gold alloy electrode
Counter electrode: Platinum electrode (built-in Pt1000 Ω RTD), the combined chlorine
insensitive version uses a silver chlorine electrode (built-in Pt1000
