TrimixBlending vs Dive Toolbox

This app allows technical divers to create custom Trimix blends (Helium, Oxygen, Nitrogen) using partial pressure blending (PPB), with support for Nitrox top-ups and ideal gas law calculations for precise gas mixing. Real Gas Calculations, uses equations of state (Van der Waals) for accurate blending. Accounts for molecular interactions and non-ideal behavior

DiveToolbox — Professional dive planning and gas calculation tools for recreational and technical divers. DECOMPRESSION DIVE PLANNER Plan single-level and multi-level dives using the Bühlmann ZH-L16C algorithm with configurable gradient factors. Get detailed ascent profiles, gas switch schedules, and comprehensive safety analysis including CNS, OTU, gas density, and END monitoring. GAS BLENDING CALCULATOR Step-by-step fill instructions for Nitrox and Trimix blending. Supports partial pressure and continuous flow methods with real-time MOD calculations. MOD / EAD / END CALCULATOR Instantly calculate Maximum Operating Depth, Equivalent Air Depth, and Equivalent Narcotic Depth for any gas mix. GRADIENT FACTORS EXPLORER Visualize how GF Low and GF High affect no-decompression limits and decompression schedules. SAC RATE CALCULATOR Calculate your Surface Air Consumption rate from dive data to improve gas planning accuracy. ROCK BOTTOM CALCULATOR Determine minimum gas reserves for safe ascent, including emergency scenarios with configurable safety margins. SUCCESSIVE DIVE PLANNER Plan repetitive dives accounting for residual nitrogen and helium tissue loading from previous dives. UNIT CONVERSIONS Convert between metric and imperial units for depth, pressure, volume, and temperature.
