Overview

The national standard COD digester follows the national standard HJ828-2017 COD Determination Method Water Quality Determination of Chemical Oxygen Demand Dichromate Method to ensure the digestion operation of reflux heating and slight boiling for 2 hours. The preparation and addition of reagent solution are consistent with the standard method to ensure reliable and accurate analysis results.

Features

Imported microcrystalline panel is adopted, which can withstand high temperature of 700 ℃, with uniform heating, fast rising/falling speed, smooth surface and easy cleaning and maintenance.
New type of high temperature resistant ceramic fiber heating plate, uniform heat receiving/conducting, less heat loss.
The glass burr return pipe and cooling system have good digestion return effect to ensure the parallelism and accuracy of digestion results.
Digital display of microcrystalline panel temperature and digestion time, temperature and timing can be set at any time.
After digestion, the equipment will automatically stop heating, and the fan will continue to work for 120 minutes to assist sample cooling, and unattended operation is allowed.
