Campbell Scientific manufactures two high-accuracy pressure transducers. The CS450 has a 316L stainless steel case that can be submerged in most canals, wells, ponds, lakes and streams. The CS455 has a rugged titanium case that allows it to be used in saltwater or other corrosive environments. The transducers feature static accuracy options of either ±0.05% FS or ±0.1% FS.
