The MSA 467895 is a high-precision, fixed-flow gas regulator designed for the calibration of MSA gas detection instruments.
Fixed 0.25 LPM Flow Rate provides a constant and accurate gas delivery that reduces gas waste by 50% compared to standard 0.50 LPM regulators.
Nickel-Plated Aluminium Construction ensures long-term durability and resistance to the harsh chemical environments often found in industrial safety applications.
Model RP Compatibility is specifically designed to fit MSA Model RP and Econo-Cal calibration cylinders with a 500 psi maximum inlet pressure.
Integrated Shut-Off Valve allows for precise control over gas delivery, ensuring the regulator only dispenses gas when the user is ready to perform a bump test or calibration.
Why does this regulator use a 0.25 LPM flow rate instead of 0.50 LPM?
MSA diffusion-based detectors are designed to calibrate accurately at lower flow rates, allowing you to save money by using half as much calibration gas per test.
Which calibration cylinders is the 467895 compatible with?
This regulator is designed for MSA Model RP style cylinders, including common 34L, 58L, and 116L aluminium or steel calibration gas bottles.
Does the regulator come with the tubing needed for the ALTAIR 4X?
Yes, the 467895 is typically shipped complete with a length of polyurethane calibration tubing to connect the regulator to your instrument.
Can I hire MSA calibration equipment or have my gas detectors serviced at PQS Survey?
Yes, we provide gas detection kits for hire and our service department offers full calibration, sensor replacement, and technical support for the MSA ALTAIR range.
Is this regulator suitable for use with reactive gases like Chlorine or Ammonia?
Standard aluminium regulators are generally not recommended for highly reactive gases; please check the specific gas cylinder requirements for stainless steel options if using NH3 or Cl2.
What is the maximum pressure this regulator can handle?
The Model RP regulator is designed for use with cylinders containing up to 500 psi of pressure.
How do I know when the cylinder is empty while using this regulator?
Most MSA calibration cylinders are used until the instrument no longer responds to the gas; however, some higher-end regulators include a pressure gauge.
Is any manual adjustment required to get the correct flow?
No, the 467895 is a fixed-flow device, meaning it automatically regulates the output to exactly 0.25 LPM once the valve is opened.
How durable is the nickel-plated finish?
The nickel plating is designed to be hardy and durable, protecting the aluminium body from corrosion and physical wear in rugged site conditions.
