Non-reagent Type Free Available Chlorine Sensor Unit FC800D

1959년부터 수처리장에서 신뢰할 수 있는 염소 측정 지원
일본 시장의 공정분석기 1위 공급 업체*

"신뢰할 수 있는 염소 모니터링 및 염소 주입 최소화"

"지속적인 자동 세척 및 유지 보수 시간 단축"

"효율적인 프로세스 관리를 위한 원격 유지 관리"

많은 고객이 이러한 문제에 직면하고 있습니다. Yokogawa 염소 분석계는 이러한 문제를 해결합니다.

FC800D 비시약형 유리 유효 염소(Free Available Chlorine) 분석계는 폴라로그래픽 방법을 채택하여 고유한 회전 전극을 통해 유리 유효 염소 농도를 온라인으로 지속 측정이 가능합니다.

FC800D는 SENCOM4.0 플랫폼 제품군의 일부이며 FLXA402T에 연결할 수 있습니다. 전극 유닛 뒤에 장착된 스마트 유닛을 활용하여 FC800D는 더 많은 통찰력을 제공할 수 있습니다.

FC800D는 펌프장, 물 공급처, 학교 및 공공시설에서의 측정에 적합합니다.

Overview:

SENCOM
Can we reduce pH dependency by using external pH sensor for compensation in the FC800D (Non-reagent Type Free Available Chlorine Sensor Unit) measurement?
(an-flxa402t-11)
Yes, you can use pH compensation for -F1 model. Please use this function in case of fluctuate pH value. If it is difficult to decide which is better, please fill pH fluctuation in the Inquiry Sheet and contact us. ...
What is the difference in construction on the electrode for F1 & C1 in the FC800D (Non-reagent Type Free Available Chlorine Sensor Unit)?
(an-flxa402t-22)
The rotating electrode material changes. -F1 = Gold electrode+celamic beads. -C1 = Gold/Platinum alloy+glass beads. They change the plateau characteristic and reduce combined chlorine sensitivity. On the other hand, available pH range becomes smaller...
What are the maintenance parts for the FC800D (Non-reagent Type Free Available Chlorine Sensor Unit)?
