Eliminating Operator Error to Ensure Safety of Technical Divers

The AII-4001 Oxygen Helium Trimix Analyzer from Analytical Industries Inc. eliminates the risk of operator error in compensating for environmental factors in analyzing gas mixtures. In a new application note, AII describe how the analyzer increases diver safety with its automatic environmental compensation.

The safety of technical divers depends upon having exactly the right mix of oxygen, nitrogen and helium for the depth and duration of their dive. Any mistake may lead to potential fatal conditions such as nitrogen narcosis or oxygen toxicity, so all checks must be as accurate as possible. However, external environmental factors – such as humidity, pressure and temperature – may affect readings and introduce errors if they are not compensated for. While standard equipment used to calibrate and make measurement on breathing gas cylinders relies on the operator to manually make these adjustments, the AII-4001 eliminates this risk of operator error. As well as sensors for oxygen and helium, it also measures pressure, humidity and temperature and uses a propriety algorithm to automatically compensate for environmental conditions.

The compact analyzer is also easy to operate, charges in under two hours and provides 16 hours of continuous operation.
