Optical Dissolved Oxygen Sensor DO70G

광학 용존 산소센서 DO70G는 하수 처리 시설 및 유출활성 슬러지 공정과 같은 수처리 설비에서 사용하도록 설계되었습니다. 

이 광학센서는 빠른 응답시간과 장기적인 안정성이 뛰어나고, 교체가 가능한 센서 캡과 케이블을 교체할 수 있어 유지보수가 용이합니다. 보정을 위해 온도 센서가 내장되어 있습니다. DO70G 센서는 PB350G/PB360G 플로팅 볼 홀더 또는 DOX8HS 침적형 홀더에서 사용할 수 있습니다.

Overview:

In a batch tank, analyzers such as dissolved oxygen (DO) analyzers, oxidation-reduction potential (ORP) meters, and mixed liquor suspended solid (MLSS) analyzers are used. To reduce the maintenance frequency, measures must be taken to prevent dirt accumulation on the sensor. As the liquid level in a tank can vary greatly, great care should be taken when selecting the sensor installation position in a tank.

Overview:

When used to measure the dissolved oxygen in an aeration tank, sensors tend to quickly become contaminated and need frequent cleaning.

Overview:

Removal of free oil and grease from a wastewater stream reduces the potential for equipment problems to occur further downstream. There are three forms of oil encountered in wastewater treatment at a refinery. 

Yes, the FLXA402 can directly power the Visiferm and DO70G. The modelcode selection for this is “D5”. It cannot be used as an analog sensor so MS code “D1” is not applicable for the Visiferm and the DO70G. D1 is available for ...
Yes, when selecting -D5(digital sensor(DO70G), FLXA402 can power an optical DO sensor.
When using analog DO sensor, e.g. DO30G, -D1 needs to be selected. When using optical DO sensor, e.g. DO70G, -D5 needs to be selected.
