제품설명


개요

HORIBA의 자동수질측정장치 TW-100은 상수시설이나 상수관, 급수관말단소에 설치해서 수질 Monitoring을 하는 System입니다. 매일 검사하는 항목(탁도, 색도, 잔류염소)를 자동 감시해서 상수의 안전한 관리를 도와줍니다. 또 이 장치는 무시약 측정, 쉬운 유지보수를 중점으로 개발했기 때문에 자동감시에 최적인 System입니다.

기능

  •  Compact하게 설계된 장치는 표준 4항목, 최대 7항목의 측정이 가능.

  •  기기의 조작은 Touch Panel로 되어 있고 대화방식의 화면설정으로 사용자가 쉽게 조작을 할 수 있습니다.

  • 유지보수를 고려한 설계로 유지보수가 용이하며 다채로운 독자기능을 탑재하여 자동계측에는 최적입니다.

  • 장거리 감시용 통신Unit를 측정장치 본체의 상부에 설치가 가능합니다.

Calibration method

See chart 1.

Automatic zero calibration

(Turbidity, color, free chlorine)
Calibration method: Measurement of filtered sample water
Trigger: Internal control (timer) or external control.
Interval: 1 to 9999 hours (can be set as desired within that range)
Time: 20~99 minutes(can be set as desired within that range)

Automatic cleaning

(Turbidity, color)
Cleaning method: Wiper cleaning
Trigger: Internal control (timer) or external control.
Interval: 5 to 9999 hours (can be set as desired within that range)
(Free chlorine)
Continuous cleaning with beads grinder

Sample water conditions

Temperature: 0 to 40°C (must not freeze)
Pressure: 0.1 to 0.75 Mpa
Flow rate: over 100 mL/min
Flow rate for measurement: 50 to 100 mL/min
* Be sure to flush the sample water before starting the system.
* Be sure to install a bypass for the pipe to which the system is attached.
* If there is any possibility that the sample water could freeze, please protect the system from cold temperature.

Ambient temperature/humidity
