Water quality testing milestones have been achieved with Intelligent Display COD Reactor. The device is manufactured by Lianhua Technology. It employs the rapid Digestive Spectrophotometric Methods developed by Lianhua’s founder in 1982 and which is now an industry standard. Lianhua COD specified water quality assessments in 10 and 20 minute intervals. Since COD assessments are crucial and are called primary indicators of water quality and pollution, getting results in these intervals enables rapid and effective decisions during municipal sewage treatment and afterwards, during the industrial waste and environmental monitoring. The Intelligent display on the reactor is user friendly, designed to augment user experience. It systematises the monitoring of test progress and results are readily displayed. This is an advantageous feature for novices in water quality testing, as well as for experienced technicians. The endless series of innovations from Lianhua Technology ensures that expectations of the industry and the customer have been met. Four decades plus of R&D ensures delivery of reliability and accuracy.
