Product Introduction

HD-SX12 graphiteCOD回流消解器It mainly consists of four parts: host, cooling device, heating device, glassware, etc. It uses microcomputer technology to timed control the heating electric furnace plate and fan, and can simultaneously heat 12 reflux devices. Graphite surface heating provides better uniformity and greater safety.

Product Features:

The HD-SX12 graphite COD digestion instrument adopts a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling and water cooling technology instead of tap water cooling. The cooling part is mainly completed by the burr condenser tube and dual fans, and the dual effect of the cooling water in the upper spherical reflux tube and the fan inside the machine ensures the reflux cooling of the sample.

Complies with the water quality COD standard "Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method" HJ828-2017.
