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.

The SW12V provides a mechanism for older dataloggers that don't have a switched 12V port to control power to the HMP45C. The SW12V is recommended for applications where the HMP45C will be measured by a CR500, CR510, 21X, CR7, or a CR10 with a silver wiring panel.

History: prior to May 2004, the HMP45C cable included a switching circuit that switched power to the sensor only during measurement, fhus conserving system power. Effective 3 May 2004, the switching circuit was removed from the HMP45C cable. The redesigned HMP45C connects to the datalogger's switched 12 V terminal. Dataloggers that do not have a switched 12 V terminal (i.e., CR500, CR510, 21X, CR10 with a silver wiring panel, or a CR7) can use a SW12V Power Switch Assembly to switch power to the HMP45C.
The 41003-5 provides a 10-plate naturally-aspirated radiation shield that houses one HMP45C probe. Its louvered construction allows air to pass freely through the shield thereby keeping the probe at or near ambient temperature. The 41003-5 attaches to a crossarm, mast, or user-supplied pipe with a 1.0" to 2.1" OD.
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.
