100 Series constant flow regulators offer unequaled quality and performance. With their unique diaphragm design, these regulators will hold their preset flow, even as the cylinder pressure is depleted. Constant flow is critical to guarantee the correct calibration of most gas detectors.
The Portages 100 series regulator is designed to maintain a constant flow rate to help ensure accurate monitor calibrations even as cylinder pressure drops. It features an N.I.S.T. traceable serial number. knurled knob for easy grip and passivated surfaces to help prevent reaction with calibration gases. The unique diaphragm design allows for a constant flow, even as cylinder volume/ pressure are depleted. It features a stainless steel gauge and a wide choice of inlets and outlets.
