Gas Miser® Demand Regulator The Gas Miser Regulator is the most advanced, yet simple-to-use calibration gas delivery system available. Made of nickel-plated brass and polished aluminum (especially important for reactive gases), the Gas Miser Regulator can supply gas flow from 0.1 lpm to 3.0 lpm. For user convenience, the regulator can stay connected to the RP Cylinder where it remains in a ready state--making it ideal for such fixed installations as work benches and calibration stations. The Gas Miser Regulator also eliminates the need to change regulators to accommodate different instruents or flow rates. Supplied with calibration tubing and special fitting.
