Multi parameter water quality analyzer LMWA-A11

Multi parameter water quality analyzer LMWA-A11

Multi parameter water quality analyzer LMWA-A11 is a high quality analyzer with benchtop design, simultaneously measures turbidity, chemical oxygen demand, ammonia and total phosphorous content of water sample. The aviation insulation protective layer present above digestion hole, effectively prevents scalds. The imported heat resistant protective cover ensures the safety and reliability of the experiment.
