This simple dual colour test strip, from our WaterWorks™ brand, allows for quick and accurate testing of Nitrates and Nitrites in water, as Nitrogen.
It has been designed with two separate test pads on the same strip. It is a simple dip and read test strip with a precise colour chart on the back of the bottle and the results are shown within 60 seconds. These strips are ideal for field, on-site and lab use as the accuracy is very high and stands out from our competitors.
No other reagents or accessories are needed for this test. We use trace amounts of chemicals on our strips which makes them extremely safe and non-hazardous. They are considered as Articles under OSHA and do not require SDS sheets.
