"physics kits"
Determine the concentrations of a wide range of gases and chemicals in the environment, whether by air, water, or soil sampling. Portable, convenient handheld units are ideally suited for field analysis of samples. All instruments are easy to use with accurate readings for reliable service. Continual testing of the environment ensures that ongoing safety measures are being enforced properly and that the integrity of the ecosystem is intact.

Nitrate Test Kits
The NED method is widely used in the quantitative analysis of nitrite and nitrate in water samples. NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, lower detection limits and measurement ranges are possible vs. chromotropic acid kits. In addition, the nitrate measurement uses only zinc which is less toxic than cadmium, making handling and disposal safer.
