New MST LS4 Series Laser Methane Sensor Express

Redefining High-precision gas detection

To Our Valued Customers and Industry Partners：
Maiya Sensor is proud to introduce the new MST LS4 Series Laser Methane Sensor, a high-precision, compact gas sensor based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). It features small size, low power consumption, and high sensitivity, making it ideal for a wide range of applications.

It is suitable for:
1.Urban gas pipeline leak detection
2.Industrial settings such as chemical plants and LNG stations
3.Environmental facilities including biogas projects and wastewater treatment plants
4.Confined space gas safety monitoring in mines, tunnels, and more

Key Features:
1.Accurate Monitoring, Free from Interference
Utilizing TDLAS technology, the sensor is highly selective only to methane, unaffected by other gases, water vapor, or dust. It offers a measurement range of 0–100% VOL, with a resolution of 0.01% VOL and an error margin as low as ±0.03% VOL (0–1%) or ±5% of the true value (1%–100%).
2.Stable and Reliable with Long Service Life
No frequent calibration is required. The sensor maintains high stability over long-term use, with a lifespan of over 5 years and an IP65 protection rating, making it suitable for various harsh environments.
3.Fast Response and Flexible Output
With a response time of ≤20 seconds, it supports both TTL serial port and 0.4V–2V analog signal outputs, enabling easy system integration and data reading.
4.Compact Design, Wide Applicability
Measuring just Φ20mm × 16.6mm and housed in a 304 stainless steel casing, it is shock-resistant, dustproof, and waterproof, suitable for both fixed and mobile detection scenarios.
