CODA-500

자동 COD 측정기

CODA-500은 JIS를 기준으로 측정 방법을 모두 자동화한 COD 장비입니다.

-직접 가열 시스템 사용으로 냉각수가 필요하지 않으며 시스템 작동에 필요한 전력을 50% 감소시켜 환경 부하를 줄이는 데 도움이 됩니다.

- 컬러 LCD 터치 스크린은 디스플레이 패널로 사용되어 조작이 편리합니다.

* COD(화학적 산소 요구량)이란?
수질 총량 규제의 규제 항목이며, BOD요구량과 함께 수중에 있는 물질 (주로 유기물)이 산화제에 의해 산화될 때 소비되는 산소량을 측정하는 것으로 물의 오염 정도를 확인하는 지표로 규정되고 있습니다.
