Product Details

Fully Automated Laboratory Water Quality Analysis System VT-7900

-Working principle:

Fully Automated Laboratory Water Quality Analysis System VT-7900isA COD fully automatic analyzer based on HJ/T 399-2007 "Determination of Chemical Oxygen Demand in Water Quality - Rapid Digestion Spectrometric Method" and USEPA digestion colorimetric method. This product integrates functions such as automatic sample/dosing, stirring, mixing, cleaning, digestion, and measurement, aiming to achieve high automation of the entire experimental process, improve the accuracy and precision of experimental data, reduce the harm of laboratory chemical reagents to experimental personnel, and ensure the safe, accurate, and effective conduct of water quality detection and analysis.

-Measurement parameters:

COD

-Typical applications:

Petrochemical, municipal, environmental protection, third-party testing and other industries

-Instrument features:

The entire process of sample pretreatment and measurement is automated, freeing up manpower and achieving unmanned operation.

● Possess the ability to pre process and measure large quantities of samples

Less reagent usage, safer and more environmentally friendly, using Hash 16mm COD pre made reagent

Using high-precision injection pumps to achieve precise sample addition and reduce manual experimental errors

● Automatically clean the inner and outer walls of the injection needle to avoid cross contamination and reduce memory effects

● Automatic stirring, easily achieving homogenization of particles and suspended solids in the sample

Intelligent human-computer interaction interface, simple and easy to use, can automatically generate reports and output data

The robotic arm automatically rotates, performs multi-point color comparison, automatically averages, eliminates measurement interference, and achieves more accurate measurements
