Gas diluents can achieve accurate dilution ratios, such as ppm or ppb levels, to meet the needs of various high-precision experiments and applications. Whether simulating specific low concentration polluted gas environments in atmospheric chemical reaction mechanism research or quality control in industrial production, accurate gas concentrations can be provided. Compared to other measurement methods, it uses the dilution principle to dilute the test gas to a safe concentration range for measurement, resulting in higher stability. Sensors, algorithms, and stable gas path design further ensure the reliability of measurement results.

Support preset dilution programs, complete multi-level dilution or complex gradient dilution with one click, reduce manual intervention, and improve work efficiency and operational convenience. Meanwhile, the intelligent operation interface makes it easier for users to set parameters and monitor the process. It has a simple and easy to understand operating interface and functions, and users only need to follow the instructions to complete the measurement of gas concentration. The miniaturized design makes it lightweight, compact, easy to carry and move, and suitable for use in various occasions.

The non-invasive measurement method will not cause contamination or damage to the measured substance, while also ensuring the safety of the user. Excellent gas path materials reduce the impact of sample residue on dilution accuracy, ensuring the accuracy and repeatability of experimental results. They are widely used in various fields such as industrial production, environmental protection, medical and health care, and scientific research, and can be used for different gas types and concentration ranges to meet diverse needs.

Measurement steps of gas diluter:

1. Zero point calibration

-Connection device: Connect the output terminal of the dynamic gas diluter to the zero calibration device.

-Adjustment and recording: Start the device and adjust the zero adjustment knob to make the output signal zero; Then record the zero point value at this time as the reference for subsequent calculations.

2. Range calibration

-Connect standard gas: Connect the standard gas to the input end of the device.

-Observe and record changes: gradually increase the flow rate of the standard gas and observe the changes in the output signal; When the output signal reaches the required value, record the range value at this time.

3. Parameter setting and flow rate setting

-Set flow rate according to demand: Based on the target concentration and total flow demand, set the flow rates of zero gas (high flow controller, such as 10L/min) and standard gas (low flow controller, such as 100ml/min).

-Calibration operation: Use certified standard gas for calibration to ensure that the indication error is ≤ 1; Record calibration results and lock parameters to avoid accidental modifications.

4. Mixed gas output

-Adequate mixing: High concentration gas samples are thoroughly mixed with pure gas in a mixer to form the desired low concentration gas sample.

-Transport usage: Transport the mixed gas through the output interface to the desired location, such as a laboratory, production line, etc.
