The 29390 is the collimator for the CS725. The need for a collimator is typically dictated by the characteristics of the intended site. The presence of wooded vegetation and man-made structures and the expected SWE for a given site are all factors. Please consult the specifications for further information.
Leer másThe following table is a guideline for determining if a site can be used without a collimator.

Max. SWE 300 to 400 mm | Max. SWE > 400 mm |
| Very open site with no proximity to trees, buildings or tall vegetation within a 48 m (160 ft) radius. | Optional | Optional | Optional |
