Product Introduction
The conventional seven parameter online analyzer is equipped with a HX-200 multi parameter controller and optional water quality conventional detection parameter sensors, including temperature/PH/conductivity/dissolved oxygen/turbidity/chlorophyll/blue-green algae, to achieve simultaneous online monitoring. The HX-200 multi parameter controller has data storage function, and users can also configure and calibrate the controller interface to achieve 4-20mA analog output, relay control, and digital communication functions.
Product Features
Realize online synchronous monitoring of multiple different parameters, improve integration, and operate at low cost;
Strong versatility, all digital sensor interfaces are universal, and analog sensors can be configured with different modules according to different sensor types;
Realize plug and play of sensors, with fast and convenient electrode installation and replacement;
Featuring 4~20mA, MODBUS RS485 multiple data output modes;
Automatically prompt errors and alarm information, and upload alarm signals;
The controller can achieve wall mounted installation/panel installation/clamp pipe installation;
The pH sensor and conductivity sensor have simple cleaning and activation, fast equilibrium speed, good repeatability and stability, and come with PT1000 temperature compensation function;
The dissolved oxygen sensor adopts breakthrough fluorescence technology, without membrane or electrolyte, basically does not require maintenance, and comes with NTC temperature compensation function;
The turbidity sensor adopts the ISO7027 standard method (infrared light scattering technology), which can eliminate the influence of sample color and can be equipped with a cleaning brush function;
Chlorophyll sensors and blue-green algae sensors are based on the fluorescence measurement of pigments to measure target parameters. They can identify potential harmful algal blooms before they occur, without the need for extraction or other processing. They can quickly detect and avoid the impact of water samples being stored.
Typical applications
Widely used for online monitoring of water quality in sewage treatment plants, waterworks, surface water, drinking water sources, aquaculture, industry, and other fields.
