BL-PT150
Portable TDLAS Methane Detector
The BL-PT150 portable methane detector uses a tunable diode laser to emit light at a wavelength absorbed by methane. By measuring how much of that light is absorbed, the device infers methane concentration. The test distance can reach 200 meters and the reaction speed is 0.02 seconds. And it combines high precision with convenient field usability, making it an ideal tool for gas leak inspection, emergency response, and routine maintenance.

Key Performance
Portable TDLAS methane detectors offer a combination of high precision, safety, and convenience, making them indispensable tools for utilities, oil & gas operators, and environmental monitoring teams seeking efficient and reliable methane leak detection.
