The Laser Methane Sensor DCH5 is based on Tunable Diode Laser Absorption Spectroscopy technology, using a high-performance probe and a specially processed gas chamber. It features high precision, high sensitivity, long life, and stable performance. Using a temperature compensation algorithm, it is unaffected by environmental interference and can work stably in harsh conditions and complex gas environments. The product adopts a modular design for easy installation and supports calibration operations via a TTL communication interface. Low power design facilitates maintenance and integration.
The ICH5 Methane Sensor is a four-channel methane sensor developed based on Non-Dispersive Infrared (NDIR) technology, which can monitor methane gas leaks in the environment in real-time. This sensor features high precision and excellent long-term stability, widely used in household gas alarms, portable gas detectors, natural gas leak detection, gas pressure regulating cabinets, and other fields.
The MCH4 methane sensor module based on MEMS gas-sensing elements is primarily used to test natural gas leaks, providing relative equivalent concentrations of methane gas in the air. Test data is communicated via I²C, UART, or high/low level interfaces. The MEMS element surface can be protected with a filter membrane. The sensor module can select pin or socket assembly as needed.
