A volume of any gas, at the same temperature and pressure, contains the same number of molecules. It is for this reason that gases are conventionally measured in Volume, in particular, the percentage (%Volume) is used for high concentrations and the part-per-million (ppm V) for low concentrations. Even if gases are different in density, there are no separate layers during the expansion. Heavy gases go downward and light gases go upward in a smooth way. Gases mainly divide in three categories: Flammable gases, Toxic gases and Inert gases.
Zeta Alarm Systems have developed the Gas Sense range of gas detectors for all flammable, Toxic and inert gases. The system consists of gas detectors installed in the area to be monitored and each one connected to a remote control panel. A fixed gas detection system should be installed to monitor areas where gases may accidentally accumulate creating hazardous conditions.This innovative detector can run as a self-contained standalone detector, or it can be linked to a central monitoring panel.
Domestic Gas Leak Detection & Protection System involved with a wall-hung household gas detection and alarm device designed to detect the concentration of combustible and toxic gases or vapors. It provides a visual and audible signal when the gas concentration reaches presetting level and reminds you to take prompt action such as startup other link equipment, ventilate gas or shut off gas supply to avoid Fire, explosion, suffocation and other evil accident.
