Product Description
Helium 500ppm Calibration Gas in Air – Custom 34L Cylinder
This Helium (He) 500ppm / Air BAL Calibration Gas – 34L is a custom-blended mixture engineered for detector calibration, verification testing, and analytical instrumentation requiring trace-level helium concentrations.
Supplied in a 34L steel cylinder at 500psi with CGA-600 valve, this specialty blend is manufactured for stable performance in laboratory environments, industrial gas monitoring programs, and quality-assurance workflows where precision matters.
As a Custom Mix, this gas is produced to order — ideal for facilities running non-standard sensor ranges, R&D programs, or compliance protocols that fall outside typical stock mixtures.
