Shenzhen Shengkian SKA12-18118745715 water quality testing instrument

Fluoride Analyzer

1. product description

The fluoride water quality analyzer adopts "ARM + microcontroller" architecture,modular hardware design,and rich expansion interfaces and communication functions,which can effectively meet the diverse customization needs of users. It occupies a small area,is easy to install,and requires low maintenance. It is the best choice for unattended applications.

In addition,the instrument's built-in cleaning system can ensure the cleanliness of the measurement flow unit,allowing users to achieve automatic control and automatic detection for several weeks without maintenance. Full-touch large-screen intelligent operating system,graphical UI design based on the detection process,the operation interface is simple and clear,easy to teach and learn. Ultra-high stability and ease of use have been rigorously tested by the market. It is mainly used in the field of online monitoring of water quality such as industrial wastewater discharge,surface water,groundwater and drinking water sources.

1. Working principle (fluorine reagent spectrophotometry)

Under acidic conditions,fluoride ions react with fluorine reagents and lanthanum nitrate to form a blue ternary complex. The absorbance is measured at a wavelength of 620 nm and converted into the corresponding concentration value.

1. Technical advantages

• Fluorine reagent spectrophotometry is not easily affected by pH changes,and the detection is more accurate and stable;

• Rich expansion interfaces and modular hardware design facilitate integrated secondary development;

• Adopt "automatic sampling and dose measurement" technology to further improve the accuracy of sampling and ensure the accuracy of test data;

• Use "cascade exhaust valve" to replace the traditional "rotary valve group" or "circular symmetrical valve group";

• Use non-contact metering injection based on "peristaltic pump + liquid level sensing" to replace the traditional contact metering injection based on "syringe pump";

• Unique optical path structure reduces the impact of "ambient temperature changes" on "light measurement" and improves measurement accuracy;

• Not afraid of harsh working environments such as high hardness,high salinity,high turbidity,and high sand content;

• Power outage protection and automatic recovery of measurements on incoming calls to avoid data loss caused by power outages;

• Equipped with regular backwashing and algae removal functions,greatly reducing instrument maintenance work.

1. System parameters

1. Paired with smart cloud platform

A water quality analyzer with high reliability,high precision,high sensitivity and life is used to ensure real-time and accurate measurement of water quality parameters,and the water quality monitoring values repackaged by the embedded controller are sent to the smart cloud platform in real time through the module. The cloud platform has the following characteristics:

Highly integrated:The water quality monitoring instrument cabinet integrates water quality monitoring sensors,acquisition modules,controllers,and modules,and reserves space for expansion.

Maintenance convenience:The cloud platform query the instrument status of each monitoring station. The water quality monitoring station adopts a modular design and has a test interface reserved to facilitate maintenance personnel to monitor the status of each instrument. There are various data output methods to meet the needs of different monitoring stations;

High stability:The system is based on an embedded operating system,and the hardware uses a high-performance core processor,which runs efficiently and is responsive;

Various installation methods(Wall mount,base,mobile mount) available;

Continuous monitoring,conduct continuous analysis of water quality monitoring nodes;

Easy to maintain,In daily maintenance,only timely addition of reagents and simple cleaning are required,and no other operations are required.
