Development of effectively test chamber for SnCl2 gas detection sensor

This paper presents the development of gas chamber for testing and characterization of gases with different concentrations. By using glass as the chamber material, it able to provide strong and air-tight structure and prevent odor chemical gases from leaking which can effect the environment. The glass chamber also enables easy monitoring (from the external) of the hardware connections, to ensure that they are always intact and in good condition. The measurement plate in the chamber consists of a copper probe, sensor, heater and conductor. A temperature within the range of 200 °C to 300 °C is required to activate the sensing mechanism. Initial testing shows that the chamber provides well enclose environment for gases detection.
