Developed using start-of-the-art design and the latest manufacturing techniques, the microprocessor based AN300 nitrogen balance analyser has been designed for specialist vehicles applications.  The application is the testing of nitrogen in vehicle tyres. Specialist applications (large aircraft, motor racing tyres, heavy machinery) use nitrogen as an inflation gas for a number of reasons; the nitrogen permeates through the tyre casing at around a third of the rate of oxygen, which keeps tyres inflated for longer. It also reduces the oxidation caused by oxygen and water vapour, thus extending the life of the tyre, and has a lower expansion rate with temperature, resulting in more even pressures under various conditions. The monitor has a stem for connecting to the tyre valve.

Featuring easy calibration, settings are secured when the lock key is pressed. In addition the low power draw allows the unit to continuously for 2000 hours on just 3 AA alkaline batteries.  The AN300 features the improved N33 oxygen sensor which provides superior long-term stability and accuracy.
