Nitrox Calculator Guide
What is the Nitrox Calculator?
The Divers Buddy Nitrox Calculator is a comprehensive tool designed to help scuba divers safely plan their dives using enriched air nitrox (EANx). This calculator provides essential information for nitrox diving including maximum operating depths, partial pressure calculations, and dive planning parameters.
Key Features
Maximum Operating Depth (MOD)
Calculate the maximum safe depth for your nitrox mix based on partial pressure limits.
Partial Pressure Analysis
Monitor oxygen partial pressure (ppO2) to ensure safe diving parameters.
Gas Mix Calculations
Work with different oxygen percentages from 21% (air) to 40% (recreational nitrox).
Safety Margins
Built-in conservative factors to ensure safe diving practices.
How to Use the Calculator
Step 1: Select Your Nitrox Mix
Choose the oxygen percentage of your nitrox mix. Common mixes include EANx32 (32% oxygen) and EANx36 (36% oxygen).
Step 2: Set Partial Pressure Limits
The calculator uses standard ppO2 limits (1.4 ATA for working depth, 1.6 ATA for contingency). These can be adjusted based on your certification level and dive plan.
Step 3: Review Calculated Values
The calculator will display your Maximum Operating Depth (MOD) and other critical values for safe nitrox diving.
Step 4: Plan Your Dive
Use the calculated MOD and other parameters to plan your dive profile and ensure you stay within safe limits.
Important Safety Information
⚠️ Safety Disclaimer
- • Always verify gas analysis before diving
- • Ensure you are properly certified for nitrox diving
- • Never exceed your training limits or certification level
- • This calculator is for planning purposes only - always follow your dive computer and training
- • Consider environmental factors and personal health when planning dives
Understanding the Results
Maximum Operating Depth (MOD)
The deepest depth you can safely dive with your chosen nitrox mix without exceeding safe oxygen partial pressure limits.
Partial Pressure of Oxygen (ppO2)
The pressure of oxygen in your breathing gas at depth. This must stay within safe limits to prevent oxygen toxicity.
Equivalent Air Depth (EAD)
The depth of air that would give the same nitrogen partial pressure as your nitrox mix at your actual depth.
