The Zetron PTM600-L is designed for highly accurate detection of methane gas, whether from buried pipeline leaks or in ambient air. It features ultra-fast response, outstanding sensitivity, and a long service life, ensuring reliable methane concentration measurement. By applying advanced wavelength-locking technology, the PTM600-L eliminates the need for routine calibration. Its compact design also enables direct installation on inspection vehicles, significantly improving leak detection efficiency.

• Smart Patrol System – Records and manages inspection data in real time

• Versatile Probes – Includes handheld and carpet probes for multiple inspection environments

• High-Flow Pump – Ensures efficient gas sampling with 1.3 L/min flow rate

• TDLAS Laser Technology – Delivers faster and more precise methane leak detection

The PTM600-L Laser Methane Detector is purpose-built for detecting methane leaks in a wide range of environments. It is widely applied in municipal underground pipeline patrols, residential and courtyard network inspections, gas stations, and long-distance transmission lines. With its 0.1-second rapid response, 1 ppm sensitivity, and vehicle-mounted or handheld flexibility, the PTM600-L ensures reliable leak detection even in complex or harsh conditions. Its rugged IP66 protection and explosion-proof design make it ideal for industries such as energy, chemical, and municipal utilities, helping safeguard infrastructure and public safety.
