Zero Air Calibration Gas

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The only way to guarantee that an instrument will detect gas accurately and reliably is to test it with a known concentration of gas.

MSDS & Certificates of Analysis
We have a MSDS for all of the blends that we sell. We use the MSDS library of Airgas, the supplier of our primary 1% NIST traceable gas standards. We also generate a Certificate of Analysis for each cylinder or frequently the CofA will cover a group of cylinders.

Product Shelf Life
• Reactive gases and blends containing at least one reactive gas – 12 months or less. (See Shelf Life Chart for exceptions)
• Non-reactive gases and blends of exclusively non-reactive gases – 36 months.
• Our labels reflect the certification date of the product.

Part Numbering System
We utilize a hybrid smart number – the part number reveals important details about the product.
Format: AA-BBB-C-DDDD

1. The first two characters (AA) define the calibration gas: “01” = Ammonia
2. The next three characters (BBB) are sequential and define the concentration.
3. The next character (C) defines the balance gas: “A” = Air, “N” = Nitrogen (N2)
4. The next characters (DDDD) define the cylinder size and material of construction:
“17S” = 17 litre steel
“34S” = 34 litre steel
“34A” = 34 litre aluminium
“58A” = 58 litre aluminium
“74A” = 74 litre aluminium
“103S” = 103 litre steel
“221S” = 221 litre steel
