eXact® Strip Micro Quaternary Ammonium (NCW-486823)
The strip has the exact amount of dry reagent necessary for the test. This reagent is to be used ONLY in conjunction with an eXact® photometer 570 nm or 638 nm. The colour or turbidity change it causes in the water is then calculated by the photometer, giving the user a fast and accurate result. This is easy to use without technical training and gives you lab-quality results.
