注:上述交叉灵敏度包含但不限于以上气体,该传感器可能对其他气体有响应。交叉灵敏度的数值可能随着传感器的生产批次和测试环境的不同而变化,本数据表仅作为参考,使用之前需要用检测气体作为标准气体进行标定。如果用交叉敏感气体进行标定,不保证标定和测量的准确性。
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.
