RepeatabilityWithin ±0.5% of the full scale (by equivalent input)
LinearityWithin ±0.5% of the full scale (by equivalent input)
Transmission
output
  • 4 mA to 20 mA DC, input/output isolated type
  • Max. load resistance: 900 Ω
  • Transmission output range: Freely settable within the measuring range
Contact outputOutputs: 2 points
Alarm contact output (R1 and R2)
 Contact type: relay contact, SPDT (1c)
 Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load)
 Contact function: Selectable from “Upper limit operation”, “lower limit operation”
   (ON/OFF control), “anomaly alarm”, “during maintenance”, and “temperature”
Calibration function
  • Air calibration and solution calibration
  • Salinity compensation (0.0% to 5.0%)
  • Temperature calibration (two points)
Transmission output hold featureSelectable from previous value hold, optional value hold or continuous (however,only the previous value hold is available in the maintenance mode)
Self-diagnosis function
