Zhongce Portable Standard Gas Dilution Device

Zhongce Portable Standard Gas Dilution DeviceMeets the requirements of JJG 915-2008 Carbon Monoxide Detection Alarm, JJG 693-2011 Combustible Gas Detection Alarm, JJG 695-2019 Hydrogen Sulfide Gas Detector, and JJG 365-2008 Electrochemical Oxygen Tester Calibration Regulations. Automatic calibration technology can make qualified judgments on its metrological performance (indication error, repeatability, alarm function, alarm value, response time, zero point and range drift), and qualified metrological performance is an important basis for accurate use.

Zhongce Portable Standard Gas Dilution DeviceThe simple gas standard device comprises a standard gas storage container 1, a zero gas storage container 2, an analytical instrument 3, and a gas mixing container 4. The standard gas storage container, the zero gas storage container 2, and the analytical instrument 3 are respectively connected to the gas mixing container 4 through a ventilation pipeline 5

The ventilation pipeline 5 includes a first channel 501 connected between the standard gas storage container 1 and the gas mixing container 4, a second channel 502 connected between the zero gas storage container 2 and the gas mixing container 4, and a third channel 503 connected between the analysis instrument 3 and the gas mixing container 4

The second channel 502 is equipped with a gas flow control switch 6 and a gas flow monitor 7, and the third channel 503 is equipped with a gas flow control switch 6. [0039] The first channel 501 includes a first main pipeline 5011, a first intake channel 5012, and a first buffer channel 5013. The first buffer channel 5013 is connected to the standard gas buffer container 8; The second channel 502 includes a second main pipeline 5021, a second intake channel 5022, and a second buffer channel 5023, which is connected to the zero gas buffer container 9

Automatic calibration technology can make qualified judgments on its metrological performance (indication error, repeatability, alarm function, alarm value, response time, zero point and range drift), and qualified metrological performance is an important basis for accurate use. The gas flow control switch 6 is located on the first main pipeline 5011 and the second main pipeline 5021, and the first intake channel

There is a first ventilation switch 10, the first buffer channel 5013 is equipped with a second ventilation switch 11, the second intake channel 5022 is equipped with a third ventilation switch 12, and the second buffer channel 5023 is equipped with a fourth ventilation switch 13.

A gas flow monitor 7 is installed on the third channel 503. The first ventilation switch 10 and the second ventilation switch 11 are not connected at the same time; The third ventilation switch 12 and the fourth ventilation switch 13 are not simultaneously turned on.

The gas flow monitor 7 is a glass rotor flowmeter with a range of 0.1L/min to 1.0L/min; The gas flow control switch 6 is a pressure reducing valve.

The ventilation duct 5 is made of silicone tubing.

The gas mixing container 4, the standard gas buffer container 1, and the zero gas buffer container 2 are aluminum foil gas collection bags 00461. The use of aluminum foil gas collection bags can ensure that they do not react with most sample gases, do not contaminate or adsorb samples, and are suitable for storing general standard gases including corrosive gases.

Zhongce Portable Standard Gas Dilution DeviceThe first intake channel 5012 and the first buffer channel 5013 are connected through a three-way joint in accordance with the first main pipeline 5011; The second main pipeline 5021, the second intake channel 5022, and the second buffer channel are connected through a 5023 tee. [0048] The first ventilation switch 10, the second ventilation switch 11, the third ventilation switch 12, and the fourth ventilation switch 13 are clips.
