Typically Ships Within 21 - 28 Days
Restockable No

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 CM225 Solar Sensor Mounting Stand attaches the SR20-L to a crossarm, mast, or pole with a 1.0" to 2.1" OD. The CM225 can be attached directly to a vertical mast or leg, but this is not recommended due to the possibility of shading or reflections from the structure adversely affecting the measurements. However, it may be possible to avoid these errors if the pyranometer is attached near the top of the structure.
The CM255 is used for mounting the SR20-L at an angle.
The CM255LS is an adjustable angle, adjustable plane mounting stand.
The 7321 is a single-channel, solid-state relay that allows a datalogger to control one or two dc devices.
The CMB200 Crossarm Brace Kit is designed to provide additional stability when using a crossarm mounted on Campbell Scientific tripods and towers. This kit provides support for crossarms with heavier or sensitive sensor loads, as well as added stability in higher winds. Each kit includes one brace arm and three sets of mounting brackets.
CM260 Adjustable Solar Sensor Mounting Kit for ATI Torque Tube
The CM260 is a fully adjustable pyranometer mounting kit. It has been specifically designed for the limited space near the end cap of the ATI Torque Tube, and it can be used with any other 12.7 cm (5 in.) diameter tube. The CM260 can be ordered with a standard top plate (same as CM255LS) for use with most common pyranometers or with a top plate designed for the VU01 ventilation unit.
Top Plate Option
-S -S w/Pyranometer Plate
-V -V w/VU01 Plate
