• High quality dual panel design with power indicator and TTL signal output indication.
• TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port).
• Analog output with increasing concentration, the higher the concentration, the higher the voltage.
• A hazardous gas detection apparatus for the family, the environment. Suitable for ammonia, aromatic compounds, sulfur, benzene vapor, and other gases harmful gas detection. Gas-sensitive element test concentration range: 10 to 1000ppm.
• Long service life, stable and reliable. Has fast response and recovery features.
