The HC2S3-QD is a rugged, accurate temperature and humidity probe that is ideal for long-term, unattended applications. The probe uses an advanced capacitive sensor to measure relative humidity. The probe includes a filter to protect the sensor from dust and particles, for superior performance and reliability.
The HC2S3-QD comes with a polyethylene filter that protects its sensor from fine dust and particles and minimizes water absorption and retention. Alternatively, a Teflon filter is available for marine environments. The response time is slower when using the Teflon filter.

大多数 Campbell Scientific 传感器的型号中都带有 –L，它表示用户指定线缆长度。如果传感器型号名称列有 –LX (这里 “X” 是其它的某个字符), 那么该传感器需要用户指定长度，但线缆尾端会配有用于某个独特系统的特殊快速接头：
如果一个传感器的主型号数字的后面没有被指定 –L 或其它的 –LX 字符，那么该传感器将具有固定的线缆长度。在产品页面订购栏中 (Ordering tab) 的描述字段的末尾，会列出线缆的长度。例如 034B-ET 型号的描述字段含有信息：Met One风传感器适用于ET气象站，67英寸线缆 (Met One Wind Set for ET Station, 67 inch Cable)。产品按固定的线缆长度做尾端处理，默认是尾线方式。
如果线缆尾端配有用于某个独特系统的特殊快速接头，则型号尾部的字符会指定该传感器用于哪一个系统。例如，034B-ET 型号表明该传感器是一个 034B 且用于 ET107 系统。
不是每一种传感器都有不同的线缆尾端选项。通过查找传感器产品页面的订购栏 (Ordering tab) 中的两个位置，可以检查某种特定传感器的可用的线缆尾端选项：
如果传感器以 –ET, –ETM, –LC, –LQ, 或 –QD 等版本的型号供应，那么线缆尾端选项已经反映在该传感器的产品型号中。例如，034B 以 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, 和 034B-QD 等型号供应。
所有其它的线缆尾端选项，如果可用，会列在该传感器产品页面的订购栏 (Ordering tab) 中的线缆尾端选项 (“Cable Termination Options) 区域。例如，034B-L 风速风向传感器具有 –CWS, –PT, 和 –PW 等线缆尾端选项，显示在 034B-L 产品页面的 订购栏 (Ordering tab) 位置。
注： 当更新的产品添加到我们的库存中时，一般来说，我们会在单个传感器的产品型号下面列出多种线缆尾端选项，而不是创建多个产品型号。例如，HC2S3-L 具有 –C 线缆尾端选项用于连接到 CS110，而我们并没有使用 HC2S3-LC 产品型号。
Campbell Scientific 的很多传感器都有可行的不同线缆尾端处理选项，包括以下几种：
注： 线缆尾端选项的可行性因传感器而异。例如，传感器可能会有 无选项、两个选项或几个选项可供选择。如果预期的选项没有列在所指定的传感器中，请联系 Campbell Scientific 的应用工程师寻求帮助。
