The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

Common Accessories

SW12V
 
The SW12V provides a mechanism for older dataloggers that don't have a switched 12V port to control power to the HMP155A. The SW12V is recommended for applications where the sensor will be measured by a CR500, CR510, 21X, CR7, or a CR10 with a silver wiring panel.
RAD14
 
The RAD14 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. It also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C (~75°F)) and low wind speeds (< 2m/s (~4.5 mph)), providing a better measurement.
41005-5
 
The 41005-5 14-Plate Gill Radiation Shield houses and protects the HMP155A Temperature and RH probe. Its louvered construction allows air to pass freely through the shield thereby keeping the probe at or near ambient temperature. The 41005-5 is white allowing it to reflect solar radiation.
