I. Product Introduction

The intelligent dual-zone digester is an independently developed dual-zone digestion system. Each zone works independently without interfering with the other, and the intelligent PID precision algorithm provides a fast temperature rise, accurate temperature control and even temperature distribution. It is suitable for the rapid heating digestion of COD, total phosphorus, total nitrogen, total chromium and other parameters in water quality testing.

II. Product Features

1	Feature 1	8-inch high-definition colour touch screen with an ergonomic operating platform and an intelligent, concise menu design.
2	Feature 2	Two independent heating zones can digest two indicators at different temperatures simultaneously or separately.
3	Feature 3	Intelligent PID temperature control technology gives even heating and a fast temperature rise.
4	Feature 4	Digestion temperature and time can be set according to the sample requirements, with preset temperature and storage functions.
5	Feature 5	Delay protection, an alarm when the temperature rise is complete and over-temperature protection.
6	Feature 6	Preset digestion programs for COD, total phosphorus, total nitrogen, sulfate and formaldehyde, which can be started with one key and are user-definable.
7	Feature 7	Transparent integrated heat-resistant and corrosion-resistant protective cover keeps the digestion state visible throughout.
8	Feature 8	Real-time display of the current temperature, maximum temperature, digestion time and remaining time.
