Professional Laser Natural Gas Detector Detecting Methane Leaks at 30 Metres in 0.1 Seconds

Do not settle for merely finding the leak; convert measurement data into a digital site record. Operating via Bluetooth with the LM100M, LeakFinder supports managing alarm levels, logging measurement information, and conducting on-site leak rate assessments via a mobile device.

The LM100M transmits a laser beam tuned to the absorption wavelength of methane toward the target surface. Light reflected back from the target returns to the optical receiver; by analysing the energy absorbed by methane molecules along the beam path, the path-integrated methane concentration is calculated in ppm×m .

Product Specifications
  • Non-Contact Methane Screening Up to 30 Metres
    Using TDLAS laser technology, the LM100M scans for methane and natural gas leaks remotely up to 30 metres without approaching the source. Difficult-to-access pipelines, elevated locations, and hazardous areas can be inspected without placing site personnel unnecessarily in harm's way.

  • 0.1-Second Response, High Sensitivity
    Accelerates wide-area surveys with a response time of just 0.1 seconds and a sensitivity of 5 ppm×m at 0–15 metres and 10 ppm×m at 15–30 metres. Methane-selective laser measurement provides professional leak survey teams with rapid and focused site inspection.

  • Up to 10 Hours of Operation in a 430-Gram Compact Housing
    Weighing approximately 430 g, the compact LM100M can operate for up to 10 hours on a full charge with its replaceable rechargeable lithium battery. Its IP65 protection rating provides a robust advantage for daily inspections in dusty, humid, and harsh field conditions.

  • Digital Leak Management with Bluetooth and LeakFinder
    Thanks to Bluetooth data transmission and the Pergam LeakFinder app, measurement data can be transferred to a mobile device; site findings can be recorded and reported more rapidly using functions such as alarm thresholds, visual/audible warnings, and leak rate estimation.

  • Ex-Certified Professional Field Instrument
    The LM100M features the II 3 (1) G Ex ic [op is Ga] IIA T4 Gc marking. Product documentation is verified under the EN 60079-0, EN 60079-11, and EN 60079-28 standards.

    Measurement and Standards Approach
    Instrument selection for methane/natural gas leak detection; walking survey, remote optical survey, vehicle-mounted mobile survey, gas selectivity, sensitivity, response time, and hazardous area classification must be evaluated jointly. For products utilising TDLAS or IR technology, current manufacturer performance, safety, and field operating documentation should serve as the baseline. Specific certification or regulatory compliance must be verified independently on a product/model basis.
