In the chemical industry, because the carbon monoxide detector can continuously detect the concentration of toxic gas, oxygen, flammable and explosive gas, and observe the gas concentration value at any time, it is widely used in petroleum, chemical industry, coal mine, metallurgy, papermaking, fire protection, municipal administration, telecommunications, food, textile and other industries. However, because they don't know much about carbon monoxide detectors, many customers don't know which one to choose when choosing. In order to solve this problem for everyone, I will introduce the selection method of carbon monoxide detectors:
1. As the name suggests, the pump-suction carbon monoxide detector is equipped with a small air pump. Its working method is that the power supply drives the air pump to extract and sample the carbon monoxide in the area to be measured, and then send the carbon monoxide into the instrument for detection. The pump-suction carbon monoxide detector is characterized by fast detection speed. When it is equipped with an external sampling handle, it can perform long-distance measurements of the dangerous area and maintain the safety of personnel. Others are the same as the diffusion gas detector.
2. Diffusion carbon monoxide detector As the name implies, the gas in the detected area slowly flows the sample gas into the instrument with the free flow of air for detection. This method is affected by the detection environment, such as ambient temperature, wind speed, etc. The advantage of the diffusion carbon monoxide detector is that the cost is relatively low.
The working principle of the pump-suction gas detector is basically the same as that of the diffusion gas detector. The carbon monoxide is detected by the carbon monoxide sensor, and then the corresponding value is displayed on the screen after being amplified and sorted by the circuit.
The above selection method of carbon monoxide detector is shared here for everyone, so if the user detects the concentration of carbon monoxide when the concentration of carbon monoxide is relatively low, it is recommended to use a diffusion carbon monoxide detector, but if the concentration of carbon monoxide is relatively high To detect the concentration of carbon monoxide or detect the concentration of carbon monoxide in a narrow space, it is recommended to use a pump-type carbon monoxide detector.
