actually happened open path gas detector pick up leaks at the lowest levels of concentration to provide an extra layer of protection and deliver a comprehensive detection solution using the UV beam the gas concentration is calculated from the amount of light absorbed and its spectral fingerprint this can detect the presence of toxic gases at different locations ranges and concentrations along the line of sight setting off a super fast alarm system at the first whiff of the leak the safe eye Quasar series detectors providing an extra layer of protection to deliver a comprehensive detection solution
