Gravity: Factory Calibrated Laser Quantitative Methane Sensor for Research (Lab-Grade CH4 Data + No Code Excel Export)

The Gravity: Factory Calibrated Laser Lab-Grade Methane Sensor offers a high-precision solution for those requiring rigorous, quantitative methane detection. Unlike traditional MQ2 sensors that rely on qualitative estimations, this sensor employs advanced Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. This technology ensures interference-free methane (CH₄) detection with precise data output reported in %LEL, making it suitable for publication and academic research.

The robust sensor guarantees credible results with its 2% LEL accuracy, meeting peer-reviewing standards. Its zero cross-gas interference capability ensures that methane readings are not compromised by other gases, such as ethanol or CO₂, prevalent in complex environments like fermenters or wastewater simulations. This attribute is crucial for producing quantitative data that can be consistently cited in research and publications.

Utilizing the Gravity: Science Data Acquisition (SCI DAQ) Module, the sensor simplifies data management with a no-programming interface for seamless reading and logging. This module automates data export into analysis-ready Excel or MATLAB files in just three clicks, eliminating the need for manual data transcription or Python scripting. Compatible with Arduino and Raspberry Pi, the setup can be deployed swiftly without the hassle of soldering or debugging, allowing a focus on primary research activities.

Designed for longevity, the methane sensor boasts 10 years of stable performance with no drift, thus removing the necessity for recalibration between experiments. Unlike electrochemical sensors that suffer from mid-trial failure due to electrolyte decay, the TDLAS technology of this sensor ensures consistent operation. Equipped with dual I2C and UART outputs, it offers seamless connectivity to a broad range of laboratory equipment and data acquisition systems, ensuring integration with custom scripts and hardware with ease.
