01
Choose a guide from the decision
Start with chart reading when you need to see relationships, with properties when choosing an input pair, with pressure when site conditions differ from standard sea level, and with processes when comparing start and end states. Each guide uses the same tested engine as the calculators.
The diagrams are original explanatory graphics, not copied chart artwork. Worked values state their pressure and mass basis, and each guide ends with an action you can perform in a connected tool.
02
Move from learning to a field workflow
The use-case library turns those concepts into sequences for commissioning, four-state airside comparison, drying and storage, altitude correction and process interpretation. It also marks where instrument quality and professional judgment remain outside the calculation.
If a claim matters to safety, compliance or equipment selection, retain the calculation record and verify it using the applicable standard, instrument procedure and qualified reviewer.
