Description
The L-Tek P100 is a laser methane detector that measures methane remotely from up to 20 m or 50 m away — point it at the target area for fast leak survey and hard-to-reach measurement points without entering the hazard area.
Extended-warranty versions are listed.
Common Applications:
Leak Survey • Pipeline Inspection • Landfill • Utilities • Oil & Gas

- Portable laser methane detector using TDLAS (Tunable Diode Laser Absorption Spectroscopy) for non-contact, long-distance leak detection
- Detects methane from up to 20 m as standard, extendable to 50 m — inspectors stay clear of high-risk areas
- Millisecond-level response (≤0.05 s) — around 1,000x faster than catalytic or electrochemical sensors
- ppm-level sensitivity (5 ppm·m) detects micro leaks
- Fingerprint spectral selectivity — no cross-interference from other gases, no false alarms, no poisoning
- Long-term calibration-free; non-contact measurement means no sensor degradation from high gas concentrations
- Compact 300 g design with USB Type-C charging; battery supports all-day inspection
- Time-stamped data logs extractable to a computer via the included USB cable for reporting and analysis
