HE-960CW

Panel-mount Type Conductivity Meter (Four-Wire Transmission, 2-channel)

HE-960CW connects conductivity sensor (ESH /FS Series) and measures conductivity and temperature in the sample water. It is ideal for the conductivity control of the purified water, pasteurized water, and water for injection that are used in the production of pharmaceuticals.
And we have developed a lineup of electric conductivity sensors that can be used in conjunction, from the conventional insertion type to the flow-through type with improved cleaning and sanitary properties.

 

Measuring range

Conductivity: 0 - 2000 μS/cm, 0 -200.0 mS/m
TDS: 0 - 2000 mg/L

  • Diverse measurement range
    The HE-960CW, which is used in conjunction with the FS Series conductivity sensor, measures the water conductivity ranging from purified to 2000 µS/cm.
  • 2-channel simultaneous measurement
    Monitoring of the desalinity rate and diagnosis of film deterioration are also possible by simultaneously measuring and comparing two locations pre- and post-processing, such as with RO film, etc.
  • 2-channel simultaneous outputs
    The HE-960CW includes 4 transmission output circuits built-in.
  • Four contact alarms
  • Built-in Communications Function (RS-485)
    The HE-960CW is equipped with an RS-485 interface to allow you to check measurements and check/change the set points from a remote location.
  • USP‹645› water quality determination function
    This product features a function that automatically determines a conductivity standard for pharmaceutical water such as an injection solvent. Temperature compensation can be achieved with various methods, or no compensation can be selected.

Transmission
output
Number of outputs: 4
4 mA to 20 mA DC/0 mA to 20 mA DC, input/output isolated type
Maximum load resistance: 900 Ω
Transmission output range: Freely selectable within the measurement range(Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.)
Contact output 
  • Number of outputs: 4
  • Alarm contact outputs (R1, R2, and R3)
      Contact type: relay contact, SPST (1a)
      Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load)
      Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis.
      Output contents: selectable from the selected measurement, USP assessment,anomaly alarm and maintenance.
  • Alarm contact output (R4)
      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 the upper/lower limit action (ON/OFF control), delay, and hysteresis.
      Output contents: selectable from the selected measurement, USP assessment,anomaly alarm and maintenance.
      (However, R1 and R2, and R3 and R4 share the common contacts respectively.)
  • Contact operation (operation between C and NO for R1 to R4)
      When selected measurement, USP assessment, or maintenance is selected in output contents:
      Contact point becomes “CLOSE” at control operation and “OPEN” at normal state (including power shutdown).
      When anomaly alarm is selected in output contents:
    Contact point becomes “CLOSE” at normal state and “OPEN” at anomaly state (including power shutdown).
      (When between C and NC is used with R4, contact point becomes reverses state with that of between C and NO.)

Calibration
function
Conductivity: Based on the specified compensation coefficient for cell constant (parameter input).
Temperature: Calibrated by comparing with the reference thermometer.
TDS: Conversion using a user-defined coefficient value (0.30 to 1.00).

  • Sensor diagnosis
    Short-circuit and disconnection of the temperature sensor
  • Out of the measurement range
  • Converter error
 
Temperature

  • Temperature characteristic of NaCl (reference temperature: 5℃ to 95℃)
  • Arbitrary temperature coefficient entry.
    (reference temperature: 5℃ to 95℃: temperature coefficient: ±5%/℃)
    (In the deionized water area, however, the temperature compensation for deionized water is automatically performed in both NaCl and arbitrary temperature coefficient compensation settings.)
