PR1 is a miniature stainless steel high purity pressure regulator. The internal volume must absolutely be at
it’s minimum. Any unswept dead volume will cause noise and instability and, will cause poor recovery time.
PR1 should be installed close to the sample point. PR1 should be installed only if there is large pressure
excursion (over 69 kPa (10 PSIG)).
