The Analox ATA pro (Advanced Trimix Analyser) is a compact, lightweight, portable monitor designed to provide fast accurate analysis of oxygen and helium concentrations in a gas mix.
Readings are shown on a scroll through display, which can be backlit if used in poor light conditions. Oxygen is measured in the range 0-100% using an Analox 9212 electrochemical sensor, which offers an expected life of 4-5 years and is provided with a 3 year graded warranty. Helium is measured in the range 0-100% using an Analox thermal conductivity sensor, which is compensated for the effect of oxygen.
Calibration is recommended prior to use and can be carried out easily and quickly using the Helium Zero Adjustment knob, the O2 Calibration knob and Analox temperature compensation chart. This ensures an accurate calibration prior to sampling. The ATA Pro is provided with an AA size battery which offers over 200 hours of use, alternatively the ATA Pro can be provided with a mains power option.
The ATA Pro is designed to be fully user maintainable, the battery and O2 sensor are field replaceable. If required, the helium sensor can be replaced and calibrated using the internal span and zero calibration adjustments in conjunction with a certified calibration gas.
