## Saturon Description
The offline HVAC charging toolkit built for the A2L era. Right number at the unit — R-410A through the new low-GWP refrigerants R-454B, R-32 and R-454C — and never a subscription.

NO SUBSCRIPTION. Pay once, yours forever. No ads, no account, no Bluetooth, no signal needed.

EVERY REFRIGERANT, INCLUDING A2L
• PT charts for R-410A, R-22, R-454B, R-32, R-454C, R-404A, R-134a, R-407C, R-290
• Bubble AND dew columns — so glide is correct on R-454C, R-407C and every blend
• Superheat reads off dew, subcooling off bubble — the way the physics actually works

CHARGE IT RIGHT
• Measured superheat and subcooling, glide-routed per refrigerant
• Target superheat for fixed-orifice systems
• Airflow / CFM (1.08 × CFM × ΔT) with the 400 CFM/ton check

WORKS IN YOUR UNITS
• °F / psig or °C / bar — one tap, remembered

BUILT FOR THE FIELD
• Big numbers readable at arm's length, gloves on
• Live results — no "calculate" button
• 100% offline, in any basement or parking lot

EVERY NUMBER SOURCED
Refrigerant data from NIST REFPROP-lineage equations of state (CoolProp), cross-checked against ASHRAE 34 and manufacturer charts — version-stamped and cited in the app. A reference aid: always confirm against the equipment's charging chart and nameplate.

For service techs, installers and apprentices working the R-410A → A2L transition.
