WS-30 Gas Sensor Test System is developed by Zhengzhou Weisheng Electronic Technology Co. It is mainly used for testing the characteristics of gas-sensitive components in experiments or mass production, and can test 30 gas-sensitive components at the same time. Through the processing of the test data, it can display the characteristics of the gas-sensitive components in two ways: graphic curve and data.

This system consists of hardware and software. According to the needs of general users, 30 data collection channels can be enabled at the same time during work, and some channels can also be selected.

The system hardware consists of PC, data acquisition module, lower computer, network cable and gas distribution box. The software is supported by Windows 7, W8, W10 and W11.

According to the user's needs, add the necessary hardware, such as automatic gas dispenser and probe table, etc. This system can automatically test the ambient temperature and humidity, and display them digitally on the main interface.
If the user needs, the test data can be stored, printed, etc., and other data processing software can be used to process the test data through data pasting. Excel worksheet can also be exported with optional test voltage, test resistance, response time, recovery time, voltage sensitivity and resistance sensitivity.


Can be used to test various semiconductor materials,mainly used for gas sensor performance test in scientific research, experiment, teaching and production


  • Adjustable Load Resistance: Optional load resistance available, measuring resistance up to 50GΩ
  • Accurate Data Analysis:Response time, recovering time, voltage, resistance and sensitivity of the components can be calculated.
  • Easy to Operate: Virtually array and number the tested components with a friendly and visual interface.
  • Data Dynamic Display: The characteristic curve of the gas sensor load output voltage changing with time can be dynamically displayed during the test.
  • Data Collection Speed Adjustable: Data collection speed can be adjusted within 1-100times/s

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
