- A portable helium oxygen analyzer designed to ensure the correct mix of helium, oxygen and nitrogen for technical diving. It analyzes gas mixes, automatically correcting for environmental conditions and eliminating the risk of errors from manual calculations.
- Displays O2, He and balance gas (0-100%)
- Automatically adjusts for environmental conditions to avoid risk of nitrogen narcosis during dives down to 46 meters
- Includes temperature, barometric pressure and RH sensors
- Long life battery with 16 hours of use, with two-hour charge time
- 15-minute auto-off feature to save battery
- Watertight, IP65 enclosure
