Protect Your Assets.


Too much chlorine causes irreversible membrane damage, too little and you’ll be cleaning more frequently from biofouling. Accuracy in your water analysis protects your assets, and now you have the control to consistently measure down to 2ppb chlorine and 6ppb sulfite with industry-first fluorescence testing methods.

Groundbreaking ULR fluorescence tests from Hach® offer easy-to-perform ultra low range tests for free or total chlorine and sulfite. The DR1300 FL and fluorescence tests are able to overcome interferences that complicate traditional colorimetric methods. You get the precision and accuracy you need.
