How to judge the performance of semiconductor gas sensor?

In the early stages of semiconductor gas sensor research, the qualification verification of semiconductor gas sensors can be simplified by using I-V characteristic analysis techniques. According to different materials, the semiconductor gas sensor has a large resistance span, covering the range of Ω~GΩ. To test semiconductor gas sensors with different gas-sensitive materials, an efficient detection scheme is required.

PRECISE High Precision Digital Source measure Meter

The high-precision digital source measure meter independently developed by Proceed has the advantages of large dynamic range and high input impedance. It can cover gas sensor test requirements in different resistance ranges from Ω to GΩ, and is the best choice for gas sensor test instruments. like:

①Real-time testing of resistance value response sensitivity of various materials under the same gas condition

②Resistance measurement with a high range span (Ω, KΩ, MΩ, GΩ) at low voltage requires high input resistance of test equipment

③I-V curve scanning

④Support R/t characteristic test of ≤40 channel gas sensitive resistance, and can record and archive.
