R Series Regulators
High Purity Calibration Gas Regulators
The R Series covers the demanding end, where the gas is at low concentration, highly reactive, or both. Single stage and dual stage versions are available in nickel plated brass or stainless steel, with the dual stage giving more consistent pressure and flow as the cylinder empties.
KEY BENEFITS
- Built for low concentration reactive gases and high purity mixtures
- Single stage version for low flow requirements
- Dual stage version for more consistent pressure and flow across the cylinder
- Nickel plated brass or stainless steel bodies
- Suits applications where a standard regulator would consume the gas before it arrives

At low concentrations the regulator stops being a delivery device and becomes part of the measurement.
A few parts per million of a reactive gas passing through an unsuitable regulator loses a meaningful proportion of its concentration to the internal surfaces. So the instrument gets calibrated against less gas than the certificate says. The lower the concentration and the more reactive the gas, the worse that gets.
The R Series addresses it with appropriate wetted materials and a construction intended for high purity work. Stainless steel is the choice for the most reactive mixtures.
The single and dual stage choice is about consistency rather than accuracy. A single stage regulator delivers well at low flow but its output shifts slightly as cylinder pressure falls. A dual stage regulator holds delivery pressure steady from a full cylinder to an almost empty one, which matters where a long or repeated calibration has to give the same result throughout.
Tell us the gas, the concentration and the instrument and we will confirm which version suits.

When the gas is at low concentration and reactive, or where high purity is required. At those concentrations an unsuitable regulator absorbs enough gas to affect the result.
Single stage suits low flow requirements. Dual stage holds delivery pressure steady as the cylinder empties, which matters on long or repeated calibrations.
Nickel plated brass or stainless steel, with stainless the choice for the most reactive mixtures.
