Calibration Gas

Each MSA Calibration Gas Cylinder is shipped with an

individual copy of a material safety data sheet (MSDS)

and an individual copy of a certificate of analysis.

 

MSA certifies that the gas mixture in 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, or volume are specified on the cylinder. The uncertainty statement of the specified nominal value is also listed.
