The BALAB SMS-215 high-temperature gas sensing system is designed to measure the gas sensitivity of resistive gas sensor materials using the two- or four-wire resistance measurement principle. The measurement system supports dynamic gas distribution systems and high vacuum pumping systems, thus facilitating the characterization of the gas-sensitive properties of the material at different concentrations (ppb or even ppt scale) and air pressures (especially oxygen pressure). The system can be used for experimental and mass production characterization of various nanomaterials, thick/thin films, pore materials, powders/particles, bulk materials, semiconductors, carbon tubes, organics, and other gas-sensitive metamaterials. The measurement accuracy and range are determined by the optional measurement instrument.
