Project Description

Online Multi-parameter Water Quality Analyzer

Product Introduction

WM-1020 series online multi-parameter water quality analyzer is an improved smart multi-parameter water quality monitoring instrument based on years of experience in design, development and production.The product can monitor water quality parameters such as pH, dissolved oxygen,conductivity,salinity, turbidity, TSS,COD, etc., and is widely used in aquaculture, tap water quality monitoring, surface water quality monitoring, marine environment monitoring and other industries.

Online Multi-parameter Water Quality Analyzer Features

  • Digital and two-way analog isolated output: the instrument provides RS485 communication interface, and the communication protocol uses standard MODBUS protocol; at the same time, the instrument has two-way analog signal outputs; the communication anti-interference ability is strong.

  • Two-way relay control: the instrument provides two-way relay control, and the control method can be customized according to customer needs.

  • Easy maintenance: customized language and menu operation interface can be provided according to customer needs.

  • Waterproof and dustproof design: protection grade is IP65, suitable for outdoor use.

  • Touch screen LCD display: it adopts 7″ touch screen display, easy to operate, can display multiple parameters at the same time, and the display is beautiful.

  • Communication method: all digital communication between sensor and controller.

  • Measurement parameters can be expanded: connect up to 199 digital water quality sensors, and the measurement of customized non-water quality parameters are available (for example: pressure, liquid level, flow, etc., the sensor needs to support the 485 communication protocol).

  • USB interface: can use USB interface to upgrade the program.

Composition

  • The instrument is divided into two parts: controller and sensor. The controller includes the main control circuit, multi-parameter measurement circuit and 7-inch touch screen, and the sensor includes various digital water quality analysis sensors.
