Gas Monitor

Gas Monitor

Workers, who work in different sectors from oil, petroleum to manufacturing and mines need, face potentially hazardous situations every day. They deserve complete safety and security from any kind of mishap can occur due to gas leakage or fire. Gas Monitor is the best gas detecting instrument designed using advanced sensor technology to provide high level safety. This is highly durable, modern and cost effective product that can measure different combustible gases from O₂, CO, SO₂, H₂S, NO₂ to many more. Its sensor comes with long lasting life than any other monitor that ensures precise output for years to come. This versatile portable product is an ideal match for different industries ranging from welding to fire fighting.
