注:上述交叉靈敏度包含但不限于以上氣體,該傳感器可能對其他氣體有響應。交叉靈敏度的數值可能隨著傳感器的生產批次和測試環境的不同而變化,本數據表僅作為參考,使用之前需要用檢測氣體作為標準氣體進行標定。如果用交叉敏感氣體進行標定,不保證標定和測量的準確性。
Notes: The cross-sensitivity includes but is not limited to the above gases. The products may response to other gases not listed here. Cross sensitivities vary according to different testing environment or production patch. The values above are given for reference only. It does not constitute a specification or an offer for sale. Customers should test under their own conditions, to ensure that the sensors are suitable for their own.
