Pressure Calculator

Pressure Calculator is designed for diamond anvil cell science and calculates pressure from various common pressure calibrants. It is lightweight, free and requires no permissions to run. Its intuitive user interface allows you to calculate the pressure in your DAC using optical and diffraction pressure markers.

Diamond edge - a choice of Akahama's 2006 or 2010 calibration

Sm:YAG and Sm:SrB4O7

For diffraction it uses the Vinet equation of state to determine pressure from lattice parameter, unit cell volume, or the angle, q or d-spacing of a chosen reflection. Equations of state for tungsten, gold, platinum, neon and copper are built in, or input your own parameters. User input equations of state parameter must be of cubic materials unless volume is used directly.

Pressure calculator is intended to be easy to use and features a dark theme for more pleasant use in unlit rooms. A full list of references is included in app, along with bug reporting and feature requests.
