Description

The Pentane (C₅H₁₂) 25% LEL + Oxygen (O₂) 20.9% Calibration Gas is a precision calibration gas mixture designed for the calibration and bump testing of compatible combustible gas and oxygen detection instruments.

This mixture contains 0.35% Pentane (C₅H₁₂), equivalent to 25% LEL, and 20.9% Oxygen (O₂), with Nitrogen (N₂) balance.

Two cylinder sizes are available with different regulator connections:

  • 34L Cylinder: CGA-600 connection
  • 103L Cylinder: C-10 connection

Please verify your required cylinder size and regulator connection before ordering.

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).

Calibration gas is NIST traceable and manufactured in the USA for accurate and reliable gas detector calibration and bump testing.

Quality & Traceability

  • NIST traceable calibration gas
  • ISO/IEC 17025:2017 – Chemical Testing
  • ISO 17034:2016 – Reference Material Production
  • QR-code access to cylinder-specific SDS and COA documentation

Common Uses: Calibration and bump testing of compatible portable and fixed combustible gas and oxygen detection instruments requiring a pentane-based calibration mixture.

Always verify the required gas concentration, cylinder connection and calibration requirements specified by the gas detector manufacturer before use.

Hazardous Material Shipping

Calibration gas cylinders are regulated for transportation and must be shipped in accordance with applicable hazardous-material transportation requirements. Available shipping methods and charges will be determined based on cylinder size, quantity and destination.

Lead Time

Please allow approximately 3 business days for order processing prior to shipment. Lead times may vary depending on availability and order quantity.

Returns

Calibration gas cylinders are non-returnable. Please verify the gas concentration, cylinder size and regulator connection before placing your order.

Important: The 34L and 103L cylinders use different regulator connections. The 34L cylinder requires a CGA-600 regulator, while the 103L cylinder requires a C-10 regulator.
