MSA ELDS Laser Open Path Gas Detector
Not missing only the target gas. ELDS, the next-generation laser detection technology.
The Senscient ELDS is a laser-based open-path gas detector that responds specifically to certain gases. Utilizing patented ELDS (Enhanced Laser Diode Spectroscopy) technology, it achieves fast and highly accurate gas detection without false alarms, even in harsh environments such as fog, rain, and vapor. It is capable of detecting a variety of flammable and toxic gases, including methane, ethylene, ammonia, carbon dioxide, hydrogen sulfide, hydrochloric acid, and sour gas (CH₄ + H₂S). Unlike conventional infrared methods, it uses a semiconductor laser light source precisely locked to the wavelength of the target gas, allowing for high-precision detection of minute leaks at the ppm level. This greatly contributes to the early detection of hazardous flammable and toxic gases and the prevention of accidents.
