The CPR-1 Series is a compact pressure regulator with most of the same interanl desigm features employed in our time proven PR-1 Series. This regulator was designed to provide optimum performance as a "lecture bottel" regulator" for pressure control in any application where a small size and low internal volume are required. The low volume allows more rapid purging in analytical instrumentaion and semiconductor doping gas applications.
