Miniature Infrared Methane Sensor KGD-SJH-210

Product Introduction

The Miniature Infrared Methane Sensor KGD-SJH-210 is an industrial-grade gas sensor used for real-time measurement of changes in gas concentration. It adopts the Non-Dispersive Infrared (NDIR) detection technology. Compared with the thermal catalytic and semiconductor principles, it has remarkable features and advantages such as a good signal-to-noise ratio, strong selectivity, immunity to cross-gas interference, high precision, excellent long-term stability, and a long service life. The sensor is compatible with both analog voltage and digital serial port outputs, meeting various usage requirements in industrial sites, laboratory measurements, etc., and is widely applied in fields such as coal mines, fire protection, urban utility tunnels, underground chambers, and pressure regulating cabinets.

Product Features

• Wide operating temperature range from -40℃ to 70℃
• Multiple measurement ranges are optional, full-range linearization, and digital output
• Ensures detection accuracy across the entire temperature and concentration range
