New gas-sensitive material testing system

The invention discloses a design for a new gas-sensitive material testing system which belongs to the gas-sensitive testing technology field and comprises a case body used to simulate the testing environment for a gas-sensitive material; a testing station placed at a middle position of the case body bottom: comprising a heating platform with MCH heating ceramic sheets and a testing probe which is a spring pressure flat head probe plated with gold on the brass surface; a testing and controlling system: using an ARM processor as the core, precisely controlling the MCH temperature through the K type thermo-coupling measured data, and performing digital-to-analog conversion of the electric signals obtained from the probe; and a host computer connecting with the hardware control circuits and capable of setting two working modes with one being gradual temperature rise and the other being constant temperature, setting the durations of the constant temperature, or the temperature rise grades and the target temperatur
