The semiconductor gas sensor basic performance required

The semiconductor gas sensor basic performance required : real-time, that is, it is better dynamic performance ; repeatability , Crankshaft Sensor Replacement can be reused many times, and good stability and long service life ; selectivity , according to the desired required to measure the gas concentration , and is not affected by other gases and interference from other substances Semiconductor gas sensor applications is very broad , and its low cost, long life use , recovery time and relatively fast response time and high sensitivity , so its use is becoming increasingly common.
