HF500 alarms are designs for the detection of liquefied petroleum gas (LPG) and natural gas (NG). It is ideal for use in private and business rooms. The HF500 can be used alone or connected to an alarm system. It comes in two variants: HF500NG for natural gas detection and HF500LPG for liquefied petroleum gas detection.

Flammable group of gases (Hydrocarbons)

Hydrocarbons

They occur in practically every segment of life. The most famous representative is natural gas (methane, CH4), and the combinations of carbon and hydrogen molecules are practically unlimited. We use them as energy sources in all endothermic processes and in almost all industries (chemical, petroleum, pharmaceutical, petrochemical). The biggest problem is their flammability and explosiveness, and for the most part, toxicity. They are one of the biggest risks in all industries. Flammability directly depends on their concentration in the air mixture and ranges between LEL - Lower Explosive Limit and UEL - Upper Explosive Limit. At concentrations of 4.4% to 17% by volume of methane in the air, the spark causes an explosion, so 4.4% v / v CH4 = 100% LEL.

The standard limits of alarm settings within the EU are Low = 10% LEL, High = 20% LEL
