Product Introduction

Usage description:

Chemical Oxygen Demand (COD) is a necessary measurement item in water cities such as surface water, industrial wastewater, and domestic sewage. It reflects the pollution caused by oxygen consuming substances in water quality

The pollution status is an important indicator and also one of the key indicators for the implementation of total emission control by the country. And the "Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method"

(HJ828 2017) is currently recognized as a relatively accurate and reliable detection method for measuring results. But the reflux digestion process of water samples is a temperature dependent

A process with strict time control, if not mastered properly, can lead to deviations in the analysis results.

Refer to HJ828-2017 method to launch this instrument

Replacing high-power electric furnaces with temperature controlled electric heaters for heating, automatic temperature control, automatic countdown for 120 minutes in micro boiling state, automatic shutdown after digestion, etc

Through technological means, the operation method is in line with the national standard method, with one click operation, automatic digestion, energy saving and consumption reduction, and simple and convenient operation.

Standard COD Reflux Digestion Instrument Compliant with National Standard HJ828-2017

● Product Name

COD intelligent reflux digestion instrument

● Model

Main technical advantages:

The digestion hole adopts microcrystalline glass digestion hole that is resistant to high temperature and strong acid and alkali corrosion, which ensures more thorough digestion and safer use;

The digestion program adopts multiple sets of heaters and an intelligent COD digestion instrument that controls their respective temperatures separately

The heating source uses far-infrared radiation for more uniform heating and thorough digestion of the sample;

Realize one click digestion, the digestion process is automatically completed, and the power is automatically turned off and the heating is stopped when the digestion is completed;

The real-time digestion temperature and reflux time of each well during the digestion process are displayed synchronously on a digital screen;

Large capacity digestion bottle design, no need for pipetting, direct titration;
