Unlike other methods which require sample collection, transportation of samples to a remote laboratory off the production floor, and the addition of DPD powders/tablets/etc., in many cases technicians can perform spot testing on the floor without violating OSHA or other safety regulations.

Using a patented and proprietary indicator, this product resists interference from monochloramines and in doing do drastically reduces the chance of getting false positive readings.
