Pergam's LPDM-15 remote methane laser detector is a compact and lightweight solution for short-range methane detection. Compact and lightweight enough to slip into your pocket and take anywhere, this instrument is powerful enough to instantly detect methane leaks up to 15 meters away.
Featuring advanced TDLAS laser technology, it offers ultra-fast response and highly selective measurements that react only to methane, even through glass. With its accurate green targeting laser, rugged aluminum housing, IP54 rating, and all-day battery life, the LPDM-15 makes monitoring methane infrastructure and facilities fast, accurate, and hassle-free.
The LPDM-15 uses TDLAS (tuning diode laser absorption spectroscopy) technology to provide accurate methane detection using a diode laser in the SWIR band. The laser emits a narrow beam of light at a wavelength corresponding to the absorption profile of methane. When the beam passes through the gas, some of the light is absorbed by the molecules. A sensor then collects the reflected light and, by analyzing the amount absorbed, the system calculates the concentration of methane while deducting the concentration still present in the atmosphere. It can thus detect, quantify, and locate leaks by tracing them back to the source through the increase in concentration.
