| 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 |
| Repeatability |
Residual Chlorine:Within ±0.05 mg/L or less Temperature: Within ±0.5˚C(for equivalent input) |
| Linearity |
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) |
| Communication capability |
RS-485 Two-wire input/output insulation type (not insulated from transmission output) |
| Temperature compensation range |
0 to 50°C |
