Overview

The national HJ828-2017 standard analysis method standardizes the determination steps of chemical oxygen demand (COD) (cr) for water quality, and strictly specifies the conditions and indicators such as heating digestion time, solution acidity, oxidant and catalyst dosage for the method. It is obvious that the determination of COD (cr) in water quality has strict conditions, and any operation that violates these conditions will affect the accuracy of the determination.

Product Details

Product Introduction

The COD automatic digestion reflux analyzer mainly consists of four parts: the body, reflux pipe, fan, and electric furnace plate. It uses microcomputer technology to control the heating of the electric furnace plate and fan in a timed manner, and can process four itemsErlenmeyer flaskThe reflux device is heated simultaneously.Timed temperature control heating electric furnace.

The instrument adopts microcomputer technology for timed control of the heating electric furnace, which can simultaneously heat 8 250ml triangular flasks. To achieve the goals of energy conservation, reducing power load, and improving efficiency.

Burr reflux pipe

Precise screw matching, smooth and easy rotation

Technical Characteristics

(1) The digestion time can be set, and after digestion is complete, the instrument automatically stops heating and can be left unattended.

(2) After the sample digestion is completed, the instrument fan continues to work to assist in cooling the sample.

(3) Replacing circulating water cooling with Feng Shui dual cooling saves electricity and water, improves efficiency, and enhances the safety of the instrument.
