TR-740Total nickel tester, nickel ion tester has been designed according to GB11910-89 "Determination of water quality nickel by butadione copper spectrophotometer" standard research and development, nickel ion in ammonium or alkaline solution is first oxidized to four values, then reacts with a colour display agent to form a complex, then by spectrophotometer to measure its absorption, after a microcomputer system treatment calculated directly to show the nickel content (mg/L).
