Msa Safety 10048279 Calibration Gas Cylinder 34L

Product Description

The MSA SAFETY 10048279 is a 34-liter aluminum calibration gas cylinder pre-filled with isobutylene at 100 parts per million (PPM), designed for use in instrument calibration and bump testing of portable gas detectors. Part of the Econo-Cal line, this cylinder delivers the same gas fill concentrations and reliability as the full-size Model RP Aluminum cylinder in a smaller, more economical package. Pressurized to 500 psig, it provides approximately 34 liters at atmospheric pressure. The cylinder measures 13.75 x 3 inches and weighs 1 pound 11 ounces. It is compatible with the Model RP Regulator.

This calibration gas cylinder is suited for use by industrial hygienists, safety technicians, and confined space entry personnel who need to calibrate or bump-test portable gas detection instruments. The Econo-Cal format is particularly practical for field service kits where portability and cost efficiency matter. Isobutylene at 100 PPM is a standard surrogate calibration gas used across a wide range of combustible gas detection instruments. Reactive gas cylinders include an expiration date printed on the label, with most cylinders carrying a 12-month shelf life from fill date.

Key Features

• Pre-filled with isobutylene at 100 PPM concentration for instrument calibration
• 34-liter capacity at atmospheric pressure in a compact aluminum cylinder
• Pressurized to 500 psig for consistent gas delivery
• Matches the gas fill concentrations of the full-size Model RP Aluminum cylinder
• Expiration date printed on cylinder to ensure calibration accuracy
• Requires Model RP Regulator for use

Compatibility

Designed for use with the MSA Model RP Regulator. Compatible with portable gas detection instruments that accept standard calibration gas cylinders with isobutylene at 100 PPM. Verify instrument requirements before use.

Installation Notes

Calibration gas cylinders should be handled and used by qualified safety technicians familiar with compressed gas cylinder procedures. Always attach the correct regulator before use — this cylinder requires the Model RP Regulator. Store cylinders upright in a cool, well-ventilated area away from heat sources, and observe the expiration date printed on the label. Check with MSA Customer Service if you need to confirm the exact shelf life for this cylinder.
