Universal 4 In 1 Hand Held Gas Detector , Multi Gas Analyzer For Coal Mines
Mining is one of the most challenging industries when it comes to protecting the health and safety of workers. There are several hazardous gases that are the product of mining and mineral processing. The main components are the flammable gas like CH4, carbon monoxide (CO), hydrogen sulphide (H2S). To minimise the risks related to exposure to hazardous gases and to ensure the safety of miners, it is essential and very important to use gas analyzers and 24h online monitoring detectors. We can provide you different models of multi gas analyzer to detect these gases in your environment and protect your safety.
