Overview

KHCOD-8G high chlorine wastewater standard COD digestion device, * in accordance with HJ/T 70-2001 high chlorine wastewater chemical oxygen demand determination CL calibration method. The $r $n instrument adopts microcomputer technology for timed control of the heating plate, which can simultaneously heat and digest 8 250ml conical flask reflux devices. The $r $n instrument adopts a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water cooling, which can save water and standardize the instrument. Preparation, operation, and COD calculation of chemical solutions for instruments. $r $n is suitable for oil fields, coastal oil refineries, oil depots, chlor alkali plants, deep-sea wastewater discharge, etc

Instructions for using the buttons on the front panel of the instrument

blowwind

Control the opening and closing of the fan.

fixedtime

Dissolve time control setting key. The instrument is set to power on for 2 hours and 30 minutes. Each press of the setting key automatically deducts 10 minutes,Determine by standard reflux methodCODThe time should be set to 2 hours.

start

Start control button for digestion. After pressing the "Start" button, the instrument will perform heating reflux digestion and automatically count down from the set value (such as 2 hours). The heating indicator light will turn on. When the set time is reached, the instrument automatically stops heating and the heating indicator light goes out.

4. The front panel of the instrument has8Only flow meters.
