Hydrogen Calibration Gas for Accurate Measurement

SpecGas Inc. custom blends hydrogen calibration gas at sub-PPM (PPB) levels, low PPM (1–100 ppm), and higher concentrations including LEL standards (e.g., 4% LEL for combustible gas detector calibration). All blends are made to exact customer specifications, ensuring the right concentration for your specific instrument or application.

Hydrogen calibration gas is available in disposable aluminum and steel cylinders, as well as refillable high-pressure aluminum, steel, and nickel-plated cylinders. Cylinder sizes range from 17 liters to 2,000 liters gas phase volume, accommodating everything from portable bump testing to high-volume industrial calibration programs.

Yes. All hydrogen calibration gas mixtures from SpecGas Inc. are NIST traceable and certified to national and international standards. This ensures traceability back to recognized measurement standards, which is required for OSHA-compliant calibration programs and accepted in research, environmental monitoring, and industrial quality assurance applications.

SpecGas hydrogen calibration gas is used to bump test and calibrate H₂-specific detectors and multi-gas monitors from leading manufacturers including MSA, Dräger, Honeywell BW, Industrial Scientific, and RKI. Custom concentration blends are available to match the exact factory calibration requirements for each instrument model.

Hydrogen calibration gas is used across a wide range of industries including semiconductor manufacturing (CVD and epitaxy processes), hydrogen fuel cell and electrolyzer facilities, petroleum refining and hydrogenation reactors, lithium-ion battery gigafactories, power generation (hydrogen-cooled generators), hydrogen refueling stations, and research and analytical laboratories requiring precise H₂ standards.

The SpecGas Stability Guarantee is backed by a proprietary internal cylinder treatment process developed over decades of specialty gas R&D. It ensures that reactive hydrogen gas mixtures maintain their certified concentration throughout the stated shelf life. If a mixture is disputed, SpecGas will provide re-analysis, investigation, and an immediate remake and re-shipment at no additional cost.
