DF Robot Calibrated Laser Quantitative Methane Sensor
The DF Robot Calibrated Laser Quantitative Methane Sensor is a lab-grade solution designed for researchers and engineers who require precise, reliable methane (CH₄) measurements. Utilizing advanced Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, it delivers interference-free, quantitative data in %LEL, eliminating the inaccuracies commonly associated with traditional gas sensors. With high accuracy and stable long-term performance, it is ideal for scientific research, environmental monitoring, and industrial analysis.
Engineered for ease of use, this sensor supports plug-and-play integration with Arduino and Raspberry Pi, while optional compatibility with the Gravity SCI DAQ module enables no-code data logging and one-click export to Excel or MATLAB. With zero cross-gas interference, fast response time, and a lifespan exceeding 10 years without recalibration, it is perfectly suited for continuous monitoring in demanding environments such as biogas systems, chemical processes, and environmental field studies.
