Connected workflows
Start with the task in front of you
Each tool uses the same state model, units and pressure context.
Calculate a state
Start from two known properties and pressure.
Start task 02Plot and compare
Label multiple states on one pressure-aware chart.
Start task 03Analyze a process
Trace heating, cooling and moisture changes.
Start task 04Mix two air streams
Balance dry-air flow, moisture and energy.

Useful for preliminary work.
Honest about its limits.
PsychroField calculates a complete moist-air state from an independent property pair, plots original chart geometry and carries the same verified state into comparisons and process balances.
It does not replace calibrated measurement, equipment selection, regulatory review or safety-critical design. Every result travels with its model, pressure and assumptions.
Field reference library
Turn readings into a defensible workflow
Five standalone sequences connect the calculations to common airside, storage and altitude decisions.
Methods you can inspect
A calculation record, not a mystery number.
The core follows the 2025 ASHRAE perfect-gas relations and retained saturation equations. It is independently compared with PsychroLib and CoolProp, with model differences documented rather than hidden.
