사양

Measuring method

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
Specified 1 to 4: 0.00 to 100.00%

Condition

For equivalent input

Temperature

Repeatability: ±0.1˚C, Linearity: ±0.5˚C

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)

Temperature compensation range

0 to 100˚C (but for 0˚C or less, 100˚C or more, extend and perform calculation)

Ambient temperature

-20 to 55˚C

Temperature compensation element

Pt 1000 (0˚C)

Calibration function

Electrical conductivity: Based on input of cell constant correction coefficient (parameter input)
 Temperature: One point calibration compared with reference thermometer

Self-diagnosis function

Sensor diagnosis error, Analyzer malfunction

Power supply

90 to 264 V AC 50/60 Hz
Power consumption 15 W or less
