Dissolved oxygen in boiler system water causes corrosion and pitting of metal surfaces, which can lead to boiler inefficiency, equipment failure, and system downtime. DEHA (N,N-Diethylhydroxylamine) is added to boiler system water as an oxygen scavenger to keep the dissolved oxygen levels as low as possible. The PDTS Method Reference: G. Frederick Smith Chemical Co., The Iron Reagents, 3rd ed., p. 47 (1980). The test kits employ the PDTS chemistry, in which DEHA reduces iron III (ferric state) to iron II (ferrous state), which readily reacts with PDTS (3-(2-pyridyl)-5,6- bis(4-phenylsulfonic acid)-1,2,4-triazine disodium salt) to form a pink-purple colored complex in direct proportion to the DEHA concentration. Test results are expressed in ppb (μg/L) or ppm (mg/L) DEHA. Kit comes in a plastic case and contains everything needed to perform 30 tests: Refill, Low and High Range Comparators, Activator Solution, 25 ml sample cup, and instructions. Range: 0-400 & 400-3000 ppb MDL: 15 ppb Method: PDTS Shelf-Life: The color comparators contained in this kit have shelf lives of 18 months. WARNING! This product can expose you to chemicals including chloroform, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
