技术说明
这个版本的HMP45C 配有快速接头，而不是尾线，可连接到MetData1气象站或CS110 电场计。探头使用HUMICAP电容型薄膜多聚物传感器来测量相对湿度，和一个PRT传感器来测量温度。 相对湿度的量程是0 到 100% RH，温度的量程是 -40° 到 +60°C。如果探头用于曝露在太阳光下的应用中，则需要防辐射罩。

兼容性
The connector can be attached to the CS110 Electric Field Meter or MetData1 Weather Station. The CS110 has a CR1000 and the MetData1 has an on-board CR10X.
Mounting
The HMP45C-LC should be housed in a 41003-5 10-plate naturally-aspirated solar radiation shield. This radiation shield mounts to a tripod or tower mast, crossarm, or user-supplied pole.
