overview

This instrument is commonly used for chemical analysis of COD, total phosphorus, total nitrogen, and total chromium detection projects that require heating and digestion.

This digestion instrument adopts intelligent PID temperature control technology, with uniform heating and fast heating time. It only takes 12 minutes to reach the set temperature; Intelligent temperature control technology, anti overheating protection system function, achieves heating temperature alarm prompt and constant temperature, and the instrument automatically alarms and reminds after digestion is completed. And equipped with TFT color LCD display screen, Chinese display, displaying parameters such as current temperature and set time; Humanized operation interface, one click selection of digestion mode, supports user-defined settings, temperature can be set to 90-200 ℃, time can be set to 0-120min, simple operation. Display parameters such as current temperature and set time; The protective cover is made of fully transparent heat-resistant material, which can directly observe the state of the water sample and ensure safe and reliable digestion.

Heating and temperature control principle

The instrument adopts PWM control for heating, and a high-sensitivity temperature probe collects the temperature of the heating block. PID technology is used for temperature control, and displayed on a TFT color LCD screen. Combined with over temperature alarm prompts, constant temperature prompts, and heating digestion completion prompts, the heating digestion temperature time is accurate and reliable.
