The Gravity: Factory Calibrated Laser Lab-Grade Methane Sensor is engineered for researchers who require reliable, quantitative data for publication. Move beyond the qualitative estimations of traditional MQ2 sensors and leverage advanced TDLAS technology for interference-proof methane (CH4) detection, with precise data output in %LEL. To streamline research workflow, the sensor features 1-click data export to analysis-ready Excel files—no coding or soldering required.
Academic-Grade Data Integrity for Credible Results
The methane sensor delivers quantitative detection with data reported in %LEL (Lower Explosive Limit), producing journal-ready statistics, producing journal-ready statistics and eliminating the vague estimates often rejected in academic review.
It features a 2% LEL accuracy, suitable for citation in the methods section of publications to meet peer-review standards. With zero cross-gas interference, the sensor ensures trustworthy data from complex environments like fermenters or wastewater simulations, where gases such as ethanol or CO2 will not compromise methane (CH4) readings.
One-Click Data Workflow to Save Weeks of Logging Time
Pairing the CH4 sensor with the Gravity: Science Data Acquisition (SCI DAQ) Module, a no-programming accessory, enables direct data reading and logging without requiring any code. The module's firmware automates data export, generating analysis-ready files for Excel or MATLAB in just three clicks and bypassing the need for manual transcription or Python scripting.
Designed for plug-and-play compatibility with Arduino and Raspberry Pi, this setup can be deployed in under 10 minutes without soldering or debugging UART codes, freeing researchers to focus on their core work. The timed data-logging feature reliably supports long-duration experiments, such as 48-hour adsorption studies, by automatically saving data even if the connected computer enters sleep mode.
Lab-Grade Durability, Seamless Connectivity to Laboratory Equipment
Engineered for longevity, the sensor offers 10 years of stable performance with no drift, eliminating the need for recalibration between experiments throughout a long-term research project. Its Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology ensures zero electrolyte decay, solving the common problem of mid-trial failure seen in electrochemical sensors. The device is equipped with dual I2C and UART outputs, enabling seamless connectivity to a wide range of laboratory equipment,data acquisition systems (DAQs), and custom Python scripts.
