Description
The CPS Calibrations 3-Gas Calibration Gas – CO 35 ppm / CO₂ 1,000 ppm / O₂ 20.9% is a precision calibration gas mixture designed for the calibration and bump testing of compatible portable and fixed gas detection instruments.
This mixture contains 35 ppm Carbon Monoxide (CO), 1,000 ppm Carbon Dioxide (CO₂), and 20.9% Oxygen (O₂), with Nitrogen (N₂) balance.
Available in the following cylinder sizes:
- 11L Aluminum Cylinder: Trigger valve
- 34L Aluminum Cylinder: C-10 connection
- 44L Aluminum Cylinder: C-10 connection
- 60L Aluminum Cylinder: C-10 connection
- 66L Aluminum Cylinder: C-10 connection
- 120L Aluminum Cylinder: C-10 connection
Please verify your required cylinder size and regulator connection before ordering.
11 Liter Minimum Order: The 11 Liter cylinder must be ordered in a minimum quantity of 6 cylinders.
Each cylinder includes a QR code for convenient access from a smartphone or other compatible device to the cylinder-specific Safety Data Sheet (SDS) and Certificate of Analysis (COA).
This calibration gas is NIST traceable and produced under quality systems supporting ISO 17034:2016 – Reference Material Production, ISO/IEC 17025:2017 – Chemical Testing, and ISO 9001:2015 – Quality Management.
