FAQ
Why do standard tube furnaces fail to accurately characterize dynamic gas sensors?
A generic tube furnace has massive dead volume, meaning it takes minutes for a target gas to reach the sensor, completely skewing the true response and recovery time (T90). The MatMeas SMS-215 features a specialized ultra-low volume testing chamber with precise mass flow controllers (MFC), allowing instant injection of trace gases for absolute, millisecond-level dynamic resistance mapping.How does the SMS-215 prevent high-temperature electrode degradation during testing?
Testing gas sensors at 500°C in corrosive atmospheres rapidly degrades standard copper or silver electrodes, ruining electrical contact. The SMS-215 utilizes high-purity platinum electrodes and a tightly sealed measurement environment, ensuring rock-solid electrical interfacing even during prolonged exposure to aggressive target gases.What is the primary measurement principle of SMS-215?
SMS-215 is designed using advanced electrical characterization methods to measure gas sensor resistance measurement with extreme precision, eliminating lead resistance and temperature fluctuations.What sample shapes and forms are supported?
The system supports standard sample geometries including solid blocks, circular thin-sheet discs, and rectangular bars with specialized test fixtures.Does SMS-215 comply with international laboratory standards?
Yes, all measurements fully align with international norms such as ASTM, IEEE, and GB/T standards to deliver publishable, research-grade data.
