Project Description

Online Multi-parameter Water Quality Analyzer

Product Introduction

Wall-mounted online multi-parameter water quality analyzer, optional water quality routine detection parameter sensor, including pH/ORP/TDS/ conductivity/salinity//dissolved oxygen/turbidity/TSS/COD/ammonia nitrogen /level etc., achieve simultaneous monitoring function. WM-1020 multi-parameter controller has data storage function, which can monitor the fields: waste water, secondary water supply, aquaculture, river water quality monitoring, and environmental water discharge monitoring.

Online Multi-parameter Water Quality Analyzer Features

  • Pluggable connection between controller and sensor, without complicated wiring.

  • Can be connected with many digital sensors, easily assembled into a conventional multi-parameter water quality analysis instrument.

  • AC 220V and DC24V power supply are optional, current is less than 500mA.

  • Fully intelligent controller, automatic sensor recognition.

  • Can calibrate the sensor both in the scene and in the lab.

  • 7.0-inch LCD touch screen display, showing beautiful, easy manipulation, can display multiple parameters in the same time.

  • Interface language can be customized, such as English, Spanish, Portuguese, Russian, Thai, Turkish, etc.

  • With functions of power-off protection and power automatic recovery, set parameters is not lost when the power is cut off.

  • No need to add reagent, no reagent consumption.
