Why Use an 89NAH Analyser for Measuring Nitrogen Gas for Tyre Purity

July 31, 2025

 

For businesses providing automotive service, performance and longevity are crucial, which is also why nitrogen tyre inflation is increasingly valued in this industry. 

But the full benefits of this service hinge on one critical factor: purity. 

Fortunately, a workshop can confidently guarantee the actual percentage of nitrogen gas for tyre applications with the help of a dedicated tool like Airtec’s 89NAH Nitrogen Analyser.

However, is nitrogen good for tyres, and how can the 89NAH Nitrogen Analyser help workshops build customer trust?

The Core Benefits of Nitrogen Tyre Inflation

The advantages of opting for nitrogen tyre inflation over conventional air include:

• Stable Tyre Air Pressure: Nitrogen molecules are larger than oxygen, significantly reducing the rate at which N2 gas escapes through tyre walls. This leads to more consistent tyre air pressure over extended periods, providing a reliable foundation for vehicle safety and reducing the frequency of top-ups.
• Prevents Internal Damage: As a dry and inert gas, nitrogen eliminates moisture and oxygen from within the tyre. This property prevents internal oxidation and corrosion of rims and tyre components. Additionally, it helps to extend the lifespan of both the tyre and the wheel, which ensures high-quality performance.
• Consistent Performance: N2 gas is less susceptible to temperature-induced pressure fluctuations than air. Consequently, there’s more uniform tyre air pressure regardless of driving conditions, contributing to predictable handling, improved fuel efficiency, and a truly precise approach to tyre maintenance.

Why Accurate Nitrogen Measurement is Indispensable 

The full benefits of a nitrogen tyre inflator are only realised when a high level of N2 gas purity is achieved and maintained within the tyre. 

However, this presents a purity challenge—even a small percentage of residual oxygen from incomplete purging can negate the key advantages, such as stable tyre air pressure and corrosion prevention. 

For this reason, relying on basic inflation processes or inferring purity from oxygen measurements has clear limitations. Often, such methods are insufficient and lack the precision required for a professional, high-quality service. 

To truly guarantee service quality and uphold the promise of quality nitrogen tyre inflation, direct and accurate measurement of the actual nitrogen gas in the tyre is essential. By investing in precise nitrogen analysers, you can deliver consistent results, effectively building customer trust. 

Airtec 89NAH: Your Precision Nitrogen Analyser

To meet the demand for verifiable high-quality nitrogen tyre inflation services, Airtec offers the 89NAH handheld Nitrogen Analyser. This definitive solution is engineered to directly measure the actual N2 gas percentage in tyres, eliminating the need for complex conversions from oxygen readings and offering unparalleled precision.

Key features and benefits that make the 89NAH an indispensable tyre pressure tool for workshops include:

• Accurate and Easy to Use: It provides quick and reliable readings with a fast reaction time, displayed clearly on a large digital screen.
• Enhanced Durability: Designed for long-term use, the unit features a battery indicator, a replaceable battery, a sensor for extended operational life, and an auto power-off function to conserve power.
• Professionalism and Trust: By enabling workshops to verify N2 gas purity, this high-quality analyser empowers them to provide a truly superior nitrogen tyre inflation service.
• A Complete Solution: Just as a tyre pressure gauge or a wall-mounted tyre inflator are critical for overall tyre care, the 89NAH completes the suite of tools for a comprehensive, precision service.

Practical Application: Using the Airtec 89NAH Analyser 

The advanced capabilities of the Airtec 89NAH Nitrogen Analyser are matched by its user-friendly design, making it a simple yet efficient tool for any workshop. And when you follow these steps, you can ensure accurate and reliable results:

• Power On and Calibrate: Press the button to power on the device. Then, hold the button for three seconds to initiate a quick calibration to the ambient N2 gas content, which it will automatically set to 79.1%.
• Sample the Tyre: Once you connect the analyser to the tyre valve, the device will quickly take a sample of the internal tyre air pressure in just a few moments.
• Read the Result: The large digital display shows the actual nitrogen tyre percentage directly, providing an accurate reading without any need for calculation.
