INTRODUCTION

The MDX500 multi-parameter water quality analyzer is a new generation of independently developed and manufactured drinking water quality monitoring equipment. It is widely applied to online water quality monitoring in urban and rural waterworks, water supply pipe networks, secondary water supply, user terminals, indoor swimming pools, large water purification equipment and direct drinking water systems. It is an essential online analysis device for waterworks production process control, water affairs management, health supervision and other fields.

FEATURES

  • 1. Multi-parameter simultaneous display and detection, monitoring turbidity, pH, ORP, temperature, conductivity, dissolved oxygen and other parameters at the same time.

  • 2. Low operation and maintenance cost, supporting remote control functions such as automatic sewage discharge and remote calibration.

  • 3. Built-in self-protection device to effectively prevent equipment damage caused by accidents and lightning strikes.

  • 4. Strong environmental adaptability; optional temperature control heating and anti-freezing module enables long-term outdoor operation in cold regions.

  • 5. Achieves long-term stable and high-precision measurement for turbidity below 1NTU.
