Advanced Pumped Laser Methane Detector with TDLAS Tech – GAOTek

Description Overview GAOTek advanced pumped laser methane detector with TDLAS technology, this product can solve the problems where the traditional detectors are encountered with, including but not limited to below problems: Slow detection speed and susceptibility to noise interference and Small leaks cannot be detected, and hidden dangers are difficult to remove Zero drift, short sensor lifespan, and easy poisoning.   Features Large flow sampling pump, can quickly locate the leakage point Adopting advanced TDLAS technology and using semiconductor laser diodes as light sources, it has good monochromaticity and achieves zero cross interference Adopting unique FOS technology, the instrument comes with a built-in reference chamber, which can lock the center wavelength of the laser in real-time, improving the accuracy and stability of system measurement The gas sample contained in the reference gas chamber, a portion of the laser beam passes through the reference gas chamber, and the center wavelength of the laser is locked by detecting the information of the reference optical path By using multiple reflection laser cavities, the effective optical path of the laser is greatly increased, thereby improving sensitivity, and even small leaks can be detected. Full range detection from O. I ppm to IOO%VOL, adjustable range, optional for automatic or manual unit switching   Application Handheld Pushcart Scooter Electric bicycle   Technical Specifications Measuring Gas CH₄ (Methane) Sensitivity 0.1 ppm Measuring Range 0.1 ppm – 100% VOL (ppm, %LEL, %VOL) Display Unit Auto switching between ppm, %LEL, and %VOL Response Time T₉₀ < 0.5s Working Temperature -20°C to 50°C Humidity <95%RH (no condensation) Ingress Protection IP65 Power Source DC 3.7V rechargeable Lithium battery Working Time 8 hours after full charge Calibration Method By built-in gas chamber Alarm Method Audible and visual signals, voice speaker Output Bluetooth Weight About 750g
