The cylinders of calibration check gas for use with Model R kits are small, lightweight steel containers approximately 10-5/8 inches high and 2-5/8 inches in diameter and, depending upon the individual pressure requirements, contain 16 to 20 liters of a specified gas mixture of a known (+/- 5% tolerance) concentration.

MSA certifies that the gas mixture in the calibration gas cylinders was prepared gravimetrically, using NIST traceable weights. The lot number and nominal value of the gas constituents in percent by volume, percent by mass, PPM mass or volume are specified on the cylinder. Each MSA calibration gas cylinder is shipped with an  individual copy of a certificate of analysis.
