electronic chlorine tester

  residual chlorine analyzer is a microprocessor-controlled instrument. The instrument is widely used in drinking water treatment plants, drinking water distribution network, a swimming pool, water treatment works, sewage treatment, water disinfection (chlorine dioxide generator package) and other process industries, aqueous solution of chlorine and temperature values continuous monitoring and control.
