제품명 2채널 전도도 측정기 HE-960CW(저농도 용)

제품설명


개요

2채널 전도도 측정기 HE-960CW는 초순수부터 2000μS/cm까지의 수질 관리로 최적인 전도도 측정기 입니다. 또한 수질 판정 기능을 가지고 있어 제약회사의 제약용수 관리로 최적입니다.

기능

  • 2채널 동시 측정 : 2개의 센서로 2가지 샘플을 동시 측정, 비교가능
  • 4점출력 : 1개의 센서에서 2점 동시출력
  • 160℃까지 표시 : 온도 모니터링 가능
  • 넓은 측정 범위로 정밀한 측정 : 0∼2μS/cm 및 0∼2000μS/cm레인지를 측정
  • 온도보상성능이 높고 반도체 분야에서 초순수 관리등으로 적합
  • 통신 기능으로 원격조작 가능 : RS-485통신 기능으로 원격 조작,제어 가능

Model

HE-960CW

Measurement method

2-electrode method

Sensor input

2-channel (for concurrent measurement with sensors isolated each other)

Temperature sensor specifications

Platinum resistance 1000Ω/0°C coefficient 3850ppm/°C standard

Temperature: 0°C to 100°C (Select your desired decimal point from 0, 1, and 2 digits)

Desalination rate: 0.0% to 100%

Conductivity difference: Depends on measurement range of sensor 2 (CH2)

Repeatability

Conductivity display : Within ±0.5% of the full scale
TDSdisplay : Within±1.5% of the full scale

(in equivalent input)

Linearity

Conductivity display : Within ±0.5% of the full scale
TDS display : Within±1.5% of the full scale

Transmission output

Number of outputs : 4
4mA to 20mA DC/0mA to 20mA DC : input/output isolated type
Maximum load resistance : 900Ω
Transmission output range : Freely selectable within the measurement range
However, repeatability and linearity will remain accurate to the separately set measuring range.
(Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.)

Contact output

Number of output : 4 points
Alarm contact output (R1,R2,R3,R4)

  • Contact type : relay contact, R1, R2, R3 : SPST
    Contact type : relay contact, R4 : SPDT
  • Contact rating : 240V AC 3A and 30V DC, 3A(resistance load)
  • Contact function : selectable from 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, R3 and R4 share the COMMON contacts respectively.)

Communication output

RS-485 input/output

Calibration function

Conductivity : Based on the specified compensation coefficient for the 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)

Transmission output hold feature

Selectable from the Previous value hold and the Optional value hold.
(However, only the previous value hold is available in the maintenance mode.)

Self-diagnosis function

·Sensor diagnosis (Short-circuit and disconnection of the temperature sensor)
·Out of the measurement range ·A/D converter scale over ·Converter error

Temperature compensation

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

Temperature compensation range

0°C to 100°C

Ambient environment

Temperature: -5°C to 55°C, Relative humidity: 20% to 85%(without dew condensation)

Power supply

Protective structure

Panel: IP65, Rear case: IP20, Terminal: IP00( Indoor-use panel installation type)

Mass

Approx. 550g

Conforming standards
