Technical Advantages

◆ Fully automatic testing: The dual heating furnaces switch automatically, and after pre-processing is completed, there is no need to wait for cooling. The testing process can be directly switched to another heating furnace without manual intervention;

Vacuum method gas path flushing: The instrument is equipped with a built-in vacuum pump. Compared with conventional gas path flushing, the vacuum method is more efficient in removing residual gases in the dead volume, reducing baseline drift, and improving testing accuracy;

◆ Temperature reference tube: The temperature sensor is placed in the temperature reference tube of the sample tube (in the same environment as the sample) to ensure high accuracy in temperature control and measurement;

◆ Automatic air cooling system: The air cooling position is equipped with air cooling pipes and temperature detectors, which automatically recognize the temperature of the heating furnace at the air cooling position and automatically turn on air cooling cooling to prepare for the next test;

◆ Support multi-step continuous automatic testing: Fully automatic execution according to the edited multi-step testing plan, used to evaluate the catalytic performance and chemical adsorption performance of materials under complex reaction conditions;

◆ Support automatic cycle testing: pre-processing+automatic cycle testing is used to evaluate the lifespan and chemical adsorption stability of materials;

◆ Ultra low temperature constant temperature&ultra-low temperature programmed heating: Ultra low temperature testing can be achieved without the need for optional ultra-low temperature configuration;

◆ Default high configuration: The default configuration includes a steam generator and a pulsating titration system;

◆ Supports 3 types of analytical gas mixing: 3 channels of analytical gas MFC, supports testing of 3 types of analytical gas mixing;

High reliability: With an international supplier system, all core components are imported
