Designed for portable calibration and analyzer applications, these metal diaphragm regulators are available in both stainless steel and brass. Low internal volumes allow for rapid purging – the Model 216 is a two-stage regulator with an internal volume of only 8.6 cc. Use the Model 216 when constant delivery pressure is desired. Brass regulators are suitable for noncorrosive service. The stainless steel models are designed for mildly corrosive service and are ideal for EPA protocol standards, low level VOC analyses, and high purity applications.
Features
Low internal volume allows rapid purging in analytical instrumentation applications
Metal diaphragms minimize diffusion of air into regulator and eliminates off gassing associated with elastomeric diaphragms, thus maintaining gas purity
High purity regulator design permits vacuum purging of regulator
Special cleaning process eliminates organic film and any surface adhering particles to ensure a stable baseline in low level VOC analyses and high purity applications
Lightweight and compact design provides for ease of transportation with small cylinders
