DMN200 industrial on line acid alkali salt concentration analyzer / controller

Brief Introduction

DMN200 series acids alkalis salt solution concentration intelligent analyzer is coupled with powerful and stable industrial microprocessor. It’s strong anti-interference and simple maintenance. DMN200 can connect with the non-contact inductive type of electrodes and then can be widely used in water treatment, chemical industrial process, paper industry and food industry. The built-in dot matrix LCD can display percentage concentration values, temperature and alarm settings. Configuration menu is simple and flexible, easy for operation.

DMN200 can be connected with digital smart electrode which made by DAMING INSTRUMENT, to achieve full digital detection and communication. Digital smart electrode build-in patented chip, can be pre-calibrated to plug and play on industrial site. Because of digital communications between DMN200 analyzer and the smart electrode, the anti-jamming ability of DMN200 analyzer is much better than the conventional conductivity analyzer. It’s especially suitable for serious industrial scene with strong interference.
