Four electrode method |
Measuring range |
Electrical conductivity: 0.0 to 200.0 mS/cm* 0.00 to 20.00 S/m*
(Switchable between fixed range (decimal point) and automatic range)
* With conditions under which temperature compensation is not performed, it is possible to display 0 to 2,000 mS/cm (0 to 200 S/m).
Temperature: 0 to 100˚C Resolution: 0.01˚C |
Salinity conversion function |
Sea water: 0.00 to 4.00%, NaCl: 0.0 to 20.0% |
Concentration conversion function |
NaOH: 0.00 to 5.00%, HNO3: 0.00 to 5.00%, H3PO4: 0.00 to 5.00

Transmission output |
Two points 4 to 20 mA DC Input/output insulated type Maximum load resistance 900 Ω |
Contact output |
Three points Non-voltage contact output Relay contact, SPDT (1c)
Contact function: R1, R2: Selectable from upper limit alarm, lower limit alarm, transmission output hold operation
FAIL: Malfunction alarm
Alarm operation: Output details: Electrical conductivity (or conversion value), temperature
Note: Range only applies to sanitary sensors. |
Contact input |
Two points Contact format: Open collector non-voltage a contact
Contact function: Transmission output range switching, transmission output hold external input
Function selectable from “Transmission 4 range selection” or “Transmission 2 range selection + hold”
Linking to selected transmission range also allows automatic switching of display |
Communication function |
RS-485 Two wire system, Input/output insulated type (not insulated for transmission output) |
