Industrial Gas Calibration Mixture — application-specific blends for process and safety
An industrial gas calibration mixture from REAL GAZ is designed for the conditions in which plant instruments actually operate. Mixtures are built around the process gas, the likely interferences and the alarm levels of safety systems.
This approach produces calibration that reflects real service, not just a laboratory ideal.
This approach produces calibration that reflects real service, not just a laboratory ideal.
For example, hydrogen service analysers often need hydrogen in nitrogen at several levels, whereas sour gas installations require hydrogen sulphide in methane. Ammonia refrigeration plants call for ammonia in air at alarm thresholds, and welding shops use argon-carbon dioxide checks. We compile these into application packs, supplied in steel or aluminium cylinders with valves suitable for corrosive or flammable service. Matching the mixture to the process avoids false alarms and missed readings. A detector exposed to hydrogen can respond differently to hydrocarbons, and a sensor in humid service may need a humidified or dry reference. We discuss the actual site conditions, including temperature, humidity and background gas, and suggest the closest practical standard. Where required we also supply cross-sensitivity checks, so maintenance teams can see how each sensor reacts to common interfering gases.
REAL GAZ supplies this product according to ISO 6142, EN 1964, EN 378 guidance for refrigeration safety and ISO 17025 practice, suitable for industrial and safety installations.
🏭 Where Industrial Calibration Mixtures Are Used
- 🧊 Ammonia refrigeration — ammonia in air for detectors protecting cold stores and processing halls;
- 🛢️ Sour gas handling — H₂S in methane or nitrogen for monitors near wells and treatment units;
- 🔩 Welding and fabrication — argon-based shielding gas analysers and oxygen checks in enclosed work;
- 💧 Water treatment — chlorine and ozone detector standards for disinfection plants.
