Product Purpose:

Product Core Features:

• Ultra-High Gas Selectivity: Adopts professional laser detection technology, only responds to methane gas, effectively eliminating interference from ethanol, formaldehyde, TVOC and other indoor mixed gases, ensuring extremely pure and accurate detection data.
• TDLAS Laser Detection & Anti-Poisoning: Based on physical laser spectral detection principle, free from chemical poisoning and aging failure. It features excellent anti-water vapor interference performance, adapts to humid indoor environments, and supports long-term stable operation without frequent calibration.
• Fast Response & High Precision: Equipped with optimized optical path and intelligent temperature compensation algorithm, with ultra-fast response speed (T90<15s) and high resolution up to 0.1%LEL. It delivers linear and stable output results in conventional household temperature and humidity environments.
• Oxygen-Independent Detection: Normal and accurate detection without relying on ambient oxygen concentration, completely solving the detection failure defect of traditional catalytic sensors in oxygen-deficient environments, with broader environmental adaptability.
• Diversified Output & Easy Integration: Supports standard 3.0V TTL UART serial port output and PWM waveform output. The communication protocol is simple and universal, compatible with mainstream single-chip microcomputers and intelligent control systems, facilitating rapid secondary development and equipment integration.
• Maintenance-Free & Long Service Life: No regular calibration required after factory calibration, with an effective service life of more than 10 years. It greatly reduces later maintenance and replacement costs, featuring outstanding long-term stability and cost performance.
• Standard Compliance & Wide Applicability: Fully compliant with national household gas detection safety standards, compact and lightweight structure, simple installation, specially optimized for household gas safety monitoring scenarios.
