3-Gas Tri-Gas Calibration Gas

3-Gas &Tri-Gas Calibration Gas Mixtures

Cal Gas Direct supplies NIST-traceable tri-gas calibration standards and precision three-component gas mixtures engineered for bump testing, routine sensor bump verification, and span calibration of multi-sensor portable and fixed gas detection systems. Whether configured for confined space safety, industrial hygiene, environmental monitoring, or specialized laboratory incubation, our 3-gas cylinders deliver consistent stability and analytical accuracy.

Engineered Multi-Component Cylinder Options

  • Common Target Blends: LEL combustible gas (Methane, Pentane, or Propane), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Oxygen (O2), and Carbon Dioxide (CO2) balanced in Nitrogen or Zero Air.
  • Portable & High-Capacity Sizes: Available in lightweight disposable cylinders (34L, 58L, 103L, 105L) with standard C-10 5/8"-18 connections, as well as high-volume returnable 600L cylinders with CGA valves (CGA 580 / CGA 590).
  • Quality & Traceability: Every cylinder includes an individual Certificate of Analysis (COA) available via the QR code on the cylinder.

Need a custom concentration, alternative balance gas, or specific regulator pairing (C-10 on-demand flow vs. fixed flow)? Contact our technical team for immediate quotes and custom blend formulation.
