It sends only the message you type and needs an internet connection. AI answers can be wrong: check them against your own readings and the equipment manufacturer's data. GOOD TO KNOW - Gauge works in US units: ยฐF, psig, CFM, inches, feet, AWG and pounds - The PT chart, calculators, reference and service log work without a connection GAUGE PRO Free: the PT chart for R-410A and R-22, the superheat, subcooling, temperature split and Ohm's Law calculators, up to 10 service calls, the AC checklist and the reference tables. Pro adds the other 8 refrigerants, the airflow, duct sizing, capacitor and voltage drop calculators, unlimited service calls with search and PDF reports, the furnace and heat pump checklists and the AI Advisor.
