Application

Tips: What industries can gas detectors be used for?

• Oil and gas: It can be used in oil and gas application sites and various industrial activity sites. When oil and gas are extracted, transported, stored and smelted, there will be flammable hydrocarbon gases with explosion risks and toxic gases such as hydrogen sulfide. Therefore, gas detector is an important instrument for exploration of drilling channels, as well as oil and gas terminals and smelters.
• Semiconductor production: In semiconductor production, phosphorus, arsenic, boron and gallium are often used as additives, and hydrogen is used as a carrier gas for reactants and reducing air. At the same time, the use of many highly toxic substances and flammable gases produces many Combustible and toxic gases make gas detectors an indispensable instrument.
• Wastewater treatment: Due to poor governance, sewage wastewater is very common in many cities and towns, and harmful gases such as methane and hydrogen sulfide are naturally emitted from sewage and wastewater, and the smell is pungent, so gas purifiers can come in handy here. .
• Hospital: There will be many toxic substances in medical laboratories and medical waste gas, and in large-scale hospitals, on-site equipment power supplies and backup power stations will be used, so gas detection equipment is required to ensure the safety and health of patients and doctors.
