[0002] With the rapid development of industrialization, various toxic and harmful gas leakage incidents occur from time to time, posing a serious threat to people's lives, property and ecological environment. Therefore, it is very important to monitor and respond to toxic and harmful gas leakage incidents in a timely and accurate manner. As an efficient gas monitoring device, the detection instrument under the toxic and harmful gas dilution device plays an important role in the emergency monitoring of toxic and harmful gas leakage.

[0003] The detection instrument under the toxic and harmful gas dilution device is a gas monitoring device based on the principle of gas dilution. It dilutes high-concentration toxic and harmful gases to a safe range and then uses a gas detector for monitoring, thereby achieving rapid and accurate detection of toxic and harmful gases. At present, the detection instrument under the toxic and harmful gas dilution device is often achieved by the solution mentioned in the patent publication number "CN219737441U". It generally includes a dilution cylinder as a portable toxic and harmful gas dilution device to dilute and detect toxic and harmful gases.
