Overview
The Inventory Master high-sensitivity gas sensor detector for air quality is a high-performance, versatile electrochemical series module that uses a three-electrode electrochemical gas sensor and a high-performance microprocessor with different gas sensors to measure the corresponding gas. It can accurately measure the gas concentration in the environment, with digital output and analog voltage output, which is convenient for users to use and debug, which greatly shortens the user’s design and development cycle. It combines electrochemical sensors and circuits to meet customers’ needs for different gas detection applications.
