Diver Benefits
True Trimix Analyser:   It displays accurate readings of Helium, Oxygen and balance gas.
Oxygen Compensation:  The ATA™  compensates for the presence of Oxygen - provides you with a more accurate Helium reading.
Greater Accuracy:  Allows you to zero the helium sensor, ensuring long term sensor accuracy.
Flexibility of Use:  Conveniently sized, the ATA™ is large enough to be viewed on a shelf, yet small enough to be portable.
Backlight as Standard:  Every ATA™ has a backlight fitted as standard, ensuring the display is easy to read even if you are diving/mixing in low light
Auto Switch Off:  The ATA™ automatically switches off after 15 minutes, allowing you enough time to check your tank but also offering peace of mind that you won't drain your battery.
Fully User Maintainable:  The ATA™ is fully user maintainable, the battery will last approx. 2 years, and both sensors are easily changeable.

Advisory Note
Replacement cells for the ATA pro should only be purchased when required. Analox do not recommend that spare cells are bought when initially purchasing your ATA pro. Electrochemical sensors are consumable items. We therefore cannot credit sensors if incorrect orders have been placed. This does not affect your warranty
