Abstract
In order to reduce the complexity of the experiment processes for the study of gas-sensing material properties, we have designed programmed temperature control gas-sensing characteristic tester. To obtain the precise measurement of gas-sensing materials’ resistance and programmed output voltage, the tester has used ratio method, SCM control technology, basic circuit principles, A/D converter, D/A conversion, the feedback network. Test results show that this system provides a great convenience for gas-sensing materials testing.
