21271 1 to 3/4-in. Pipe Reducer Fitting


The 21271 is used to attach an older NR01 net radiometer (serial numbers less than 2313) to a CM204 or CM206 crossarm. Campbell Scientific recommends mounting the crossarm to a CM300-series mounting pole at least 25 ft away from other mounting structures.

The 21271 pipe reducer fitting was also a component of the 19455 CNR2 Mounting Kit, which was retired on December 23, 2009.
