Characteristic Structure 

Technical Advantages

• Full automatic test：dual heating furnace automatic switching, no need to wait for pre-treatment cooling, directly switch to the other furnace for testing, without human intervention;
• Vacuum clean residual gas: built-in vacuum pump to remove residual gas in free space, reduce baseline drift and improve test accuracy;
• Temperature reference tube: temperature sensor is placed in reference tube of the sample tube (the sensor and sample are in the same environment), ensure high accuracy of temperature control and measurement.
• Automatic air-cooled cooling system:equipped with an air-cooled tube and a temperature detector at the air-cooled site, automatically detect the temperature of the heating furnace and turn on the air-cooled cooling system to prepare for the next test;
• Multi-step continuous automatic test: fully automatic execute edited multi-step test program, used to evaluate the catalytic performance and chemical adsorption performance of materials under complex reaction conditions;
• Automatic cycle test: pre-treatment and test automatically cycle, used to evaluate the lifetime and chemisorption stability of materials;
• Support ultra-low temperature thermostat & ultra-low temperature programmed temperature rising, realize ultra-low temp test;
• High standard configuration: standard vapor generator, pulsed titration system;
• Support test of mixing 3 analysis gas, standard 3 gas MFC and support 3-gas mixture test;
• High reliability and durability;
