2.Gas Sensor Testing System/Gas Sensor Testing Platform/Testing SystemH18427

Mainly used for testing the characteristics of gas sensors in experiments or mass production. By processing the test data, the characteristics of gas sensors can be displayed in two ways: graphical curves and data
★ Can display the load output voltage of gas sensing components;
★ Able to calculate component voltage sensitivity:
★ Virtual array and numbering of tested components with a friendly and visual interface:
★ It can classify components according to measurement results, visually represent them in different colors on a virtual array, and calculate the ratio of the number of components in each range to the number of components participating in the test, expressed as a percentage. It can dynamically display the characteristic curve of the output voltage of the gas sensor load over time during the testing process.
This system can also virtually set the load resistance, which only requires one test of the components,
Then, by setting a virtual resistor, it is possible to calculate and observe the gas sensing element and different load resistances (virtual)
Characteristic parameters during series connection.
If required by the user, the test data can be stored, printed, and processed using other data processing software through data pasting.
