A new development, based on the very successful CR:243 range of products,
the CR:243/4 "Noise Pole" has proved reliable after its first
installation at an international airport in the UK. Cirrus has now announced
it as a standard product to add to its large range of hand-held, portable
and fixed installation environmental analyzers.
For more information on this product, please see the CR:243/4
Noise Pole information page.
