High precision automatic mixing systemTechnical advantages and application scenarios:

Technical advantages:

High precision: Flow control accuracy within ± 0.5%, concentration ratio error ≤ ± 1%, meeting scientific research level requirements.

Wide dilution ratio: supports large dilution ratios of 100:1 to 10000:1, and can prepare ppb level standard gases (such as 10 ppb gas diluted 100 times with 1 ppm gas).

Easy to operate: fully automatic operation, reducing manual intervention, supporting one click calibration and self diagnosis, reducing maintenance costs.

Safe and reliable: Explosion proof design, emergency shut-off device, and redundant control logic ensure the safety of hydrogen and other gas mixing processes.

Application Scenario:

Research experiment:

Prepare specific ratio mixed gases (such as hydrogen/nitrogen, methane/air) for catalytic reactions, material performance testing, etc.

Simulate complex environmental conditions (such as atmospheric pollution components, industrial waste gas composition) and support calibration of environmental monitoring equipment.

Industrial production:

Chemical industry: Optimize gas ratios for processes such as ammonia synthesis and hydrogenation reactions to improve product purity and yield.

Semiconductor manufacturing: controlling the atmosphere composition of photolithography, etching and other processes to improve product consistency.

Medical and Environmental Protection:

Medical gas dispensing (such as anesthesia gas, ventilator gas) to ensure patient safety.

Calibration of environmental monitoring stations to ensure the accuracy of PM2.5, VOCs and other pollutant detection data.

Energy sector:

Fuel cell testing: Accurately control the hydrogen/air ratio to evaluate battery performance and lifespan.

Hydrogen energy research and development: Preparation of high-purity hydrogen gas mixture, supporting testing of hydrogen storage materials, hydrogen refueling stations, and other scenarios.
