Calibration Gas S₂+ He

CALIBRATION GAS S₂+ HE — reference blend for accurate instrument calibration

Calibration Gas S₂+ He from REAL GAZ is a reference mixture with a helium balance, prepared so that analysers and detectors can be set to a known, traceable response. A calibration gas is only as good as its stated concentration and uncertainty, so both appear on the certificate that accompanies each cylinder.
Zero and span points can be supplied together, allowing technicians to calibrate and verify in a single visit.

REAL GAZ supplies this product according to ISO 6142, ISO 6143 and ISO 17025, with stability testing following ISO 12963, suitable for industrial and laboratory use.

🏭 Where S₂+ He Calibration Gas Are Used

⚙️ Fixed gas detectors — plant safety systems are bump-tested and calibrated at scheduled intervals;
🔬 Laboratory analysers — calibration curves are built from several certified concentrations;
🏥 Portable monitors — service engineers calibrate handheld instruments in the field;
🚀 Method validation — laboratories demonstrate accuracy and repeatability against a reference standard.

💡 Why Choose REAL GAZ

✅ Stated uncertainty — each certificate gives concentration, tolerance and expanded uncertainty;
🧪 Stable in storage — cylinder treatment and component choice limit change over the shelf life;
🎯 Zero and span sets — matching blends reduce the number of orders and deliveries;
🔒 Traceable records — batch numbers link every cylinder to its weighing and analysis data;
📄 Certificate of Analysis (CoA) — supplied with every order.

🔬 Quality Control & Safety

multi-stage purification of the helium and components;
precision gravimetric blending with uncertainty budgets;
moisture & impurity analysis plus verification against reference standards;
leak testing and pressure integrity checks.

Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.

Record the lot number and expiry date in the calibration log each time. If the reading drifts after a change of cylinder, check the regulator and tubing before suspecting the instrument. Where regulations require periodic recalibration of detectors, we can set up a delivery calendar aligned with your service intervals, together with the certificates your inspector will ask to see. Our dispatch team packs every order with protective caps, checks the cylinder label against the order and attaches the analysis certificate, so that goods can be received and put into service without delay. If you are unsure which specification is appropriate, a short call with our technical staff will usually settle the question before any gas is blended.

⚙️ Trusted Gas Solutions

REAL GAZ delivers Calibration Gas S₂+ He to maintenance teams, laboratories and safety departments in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Use the gas before the expiry date, apply the correct flow rate for your instrument and allow the reading to stabilise before adjusting. Calibration tubing should be short, leak-free and made of a material that does not adsorb the component of interest.

REAL GAZ — reference gases that make measurements defensible.
