DEHA CHEMets® Visual Test Kit - 0-400 & 400-3000 ppb DEHA CHEMets® test kit allows for easy and accurate determination of DEHA concentration in water. The sample is treated with ferric iron, and DEHA reacts with it to form a pink-purple complex, indicating the concentration. Results are expressed as ppb or ppm. This test method is temperature dependent. High sample temperatures may cause false positive test results. For best accuracy, sample temperatures should be 20 ± 3 degrees Celcius. Range: 0-400 & 400-3000 ppbMDL: 15 ppbMethod: PDTS Shelf life: The color comparators contained in this kit have shelf lives of 18 months.
