1- x 1-in. Nu-Rail Crossover Fitting
This fitting can be used as an alternative to the CM220 for mounting the SR50 to a CM206 crossarm.
OrderableCM221
Right-Angle Mounting Kit
The CM221 mounts a pipe or tube at 90° to another pipe or tube. It is typically used to attach a sensor with a vertical pipe (including most wind sensors) to a crossarm. The cast aluminum, right-angle mounting bracket has 3.8 cm (1.5 in.) U-bolts and hardware and will accommodate tubing with a 1- to 1.5-in. outer diameter.
OrderableCM230
Adjustable Inclination Mounting Kit
If the surface is at an angle, the CM230 Adjustable Inclination Mount is used to position the SR50 so that it is perpendicular to the ground.

Replacement Parts
(3)42816
1/2-Unit Desiccant Bags (quantity of 10)
The 42816 desiccant is used to desiccate small subassemblies. For example, the KH20 Krypton Hygrometer and the base of the CR3000 Measurement and Control Datalogger each require two bags. Multi-packs are recommended for customers who need to desiccate multiple enclosures or systems.
Orderable42945
1 g Bag of Desiccant (quantity of 10)
These replacement desiccant packs are used inside the SR50's transducer. Two packs are used each time the desiccant is replaced.
Orderable10970
Replacement Transducer Kit for SR50 or UDG01
The 10970 Transducer Kit is comprised of one replacement transducer with connector, an O-ring, 2 [#4091] desiccant packs, and 2 [#905] desiccant packs. The 10970 can typically be replaced in the field by a customer (assumes reasonably favorable weather conditions).
