• Ammonia (NH₃): Ideal for gas detection in industrial and environmental settings.
• Chlorine (Cl₂): Critical for calibration in water treatment and safety applications.

Multi-Gas Mixtures

Designed for multi-gas detectors used in industrial and environmental monitoring. Our quad and quint mixtures include combinations like:

• H₂S, SO₂, CH₄, CO, CO₂, O₂ in N₂: Tailored for versatile testing needs across multiple applications.

Non-Reactive Gases

We supply a range of non-reactive gases, including:

• Nitrogen (N₂)
• Methane (CH₄)
• Propane (C₃H₈)
• Helium (He)
• Hydrogen (H₂)
• Carbon Dioxide (CO₂)
• Sulphur Hexafluoride (SF₆).

These gases are ideal for calibration in industrial and laboratory environments.

Specialty Gases

Our specialty gases are designed for precise calibration in specialised applications:

• Ethanol (C₂H₅OH): Widely used in breath testing, manufacturing, and research calibration.
• Hydrogen Chloride (HCl): Applied in chemical manufacturing safety calibration.
• Hydrogen Cyanide (HCN): Vital for mining and industrial gas detection systems.
• Nitric Oxide (NO) and Nitrogen Dioxide (NO₂): Common in air quality and environmental monitoring.

At AccuSpan, we offer a comprehensive range of Non-Refillable Cylinders (NRCs) and High-Pressure Refillable Cylinders (HPCs) to suit your operational needs:

• 112-Litre NRCs (112DA): Ideal for applications requiring a larger gas volume, providing an extended supply for comprehensive calibration tasks.
• 60-Litre NRCs (60DA): Suitable for applications requiring moderate gas volumes.
• 34-Litre NRCs (34DA): Offers a balance between portability and capacity, ideal for regular calibration procedures.
• 12-Litre NRCs (12DA): Ultra-portable and low-cost, designed for quick and convenient calibrations in confined or remote locations.
• 375-Litre NRCs (375DA): NEW! Our highest-volume non-refillable cylinder, designed for workshop or remote locations where transport costs are high.

In addition, we provide High-Pressure Refillable Cylinders (HPCs), which are an excellent choice for applications that demand larger gas volumes and longer usage periods. These durable, cost-effective, and reusable cylinders are ideal for facilities with frequent calibration needs. Learn more on our HPC product page.

Calibration gases are widely used across many industries, including:

• Industrial Safety: Gas detectors in factories, refineries, and chemical plants rely on proper calibration to protect workers from toxic or explosive gases.
• Marine: Gas detection on vessels using both NRCs and HPCs for fixed and portable gas detectors. These gases are increasingly used for stack emissions, especially for NOx and SOx.
• Oil & Gas: Supports compliance with safety requirements for gas detection in offshore rigs, petrochemical facilities, pipelines, refineries, and mud logging applications.
• Environmental Monitoring: Essential for accurate readings in air quality monitoring stations and environmental assessments.
• Research and Development: Ensures precise gas measurements in laboratories and testing facilities.
