4 Best Industrial SO2 Gas Detectors

User:JXCTUpload time:Sep 19 2022
Why do you need a gas detector?

In the process of industrial production, flammable, toxic, harmful gas leakage occurs from time to time, will cause serious threats to personnel, equipment, production, life. The main causes of leakage are: 1. Material defects in production equipment or containers. 2. The sealing ring and the sealing ring are not tightly sealed. 3. The welding place of the container is subjected to electrochemical corrosion for a long time. 4. Human negligence, etc. Leaking flammable or toxic gases are quickly diluted by air, so the location of the leak is difficult to find and even more difficult to quantify. Over time, these gases can build up in certain areas or in certain blind spots. When the content of combustible gas in the air reaches a certain value, it is easy to burn or explode in the presence of open fire. If this very dangerous hidden danger can not be found in time, it will bring great loss to personal safety and property. At this time, we can use industrial gas detector for online monitoring.

Why pay attention to gas monitoring

To predict this potential hazard, you can install more gas detectors in living and production areas with potential leakage hazards. These can continuously measure whether the flammable gas in the air around the equipment has reached combustion or explosion concentrations. As soon as the gas sensor detects the presence of flammable or toxic gas, it immediately responds by displaying the reading, issuing an alert, or sending an alert to your phone. Let people take immediate measures to deal with the leak, on the other hand, disperse the surrounding air, reduce the concentration of combustible gases in the air, and avoid a serious accident.
