Measuring method


Measuring range

Residual Chlorine: 0 mg/L to 3 mg/L   Resolution: 0.01 mg/L
Temperature: 0 to 50˚C   Resolution: 0.1˚C


Residual Chlorine:Within ±0.05 mg/L or less   Temperature: Within ±0.5˚C(for equivalent input)


Residual Chlorine:Within ±0.05 mg/L or less   Temperature: Within ±0.5˚C(for equivalent input)

Transmission output

Two points 4 to 20 mA DC   Input/output insulation type   Maximum load resistance 900 Ω

Contact output

Three points No-voltage contact output Relay contact, SPDT
Contact capability R1, R2: Selectable from upper limit alarm, lower limit alarm, ON/OFF control, currently holding transmission output, and cleaning output.
(opened at alarm operation, closed usually, closed at power-off)
 FAIL: Error warning (normally closed; open when an error occurs; open when the power is turned OFF)

Contact input

Two points Contact type: No-voltage a contact for open collector
Contact capability: Input 1: External input for transmission holding
 Input 2: Flow switch input for interlock(Open due to decreased flow)
