HVAC Refrigerant P-T Chart provides instant pressure-temperature lookup for HVAC technicians and AC service professionals. Instant pressure-temperature lookup for 10 EPA 608 refrigerants including R-454B (next-gen EPA transition replacement) and R-32 mini-split systems with NIST REFPROP-grade saturation data cross-checked against Honeywell, Chemours, and Arkema P-T charts. FEATURES: Bidirectional Lookup - Pressure → Temp and Temp → Pressure 10 Refrigerants Supported - R-410A, R-22, R-454B, R-32, R-407C, R-134a, R-404A, R-507A, R-290, R-717 Full P-T Saturation Tables - -60°F to +150°F in 5°F steps Bubble & Dew Points - Zeotropic blend data (R-454B, R-407C, R-404A) Temperature Glide Display - Shows glide range for blends Linear Interpolation - Precise results between data points 100% OFFLINE OPERATION: Works without internet connection. All saturation data built into the app - no server calls, no delays. Perfect for job sites without cellular coverage. HOW IT WORKS: 1. Select your refrigerant (R-410A, R-454B, R-32, etc.) 2. Choose lookup: Pressure → Temp or Temp → Pressure 3. Enter your value (PSIG or °F) 4. Get instant saturation results with bubble/dew for blends WHY YOU NEED THIS APP FOR AC SERVICE: Every air conditioning service call requires instant saturation temperature verification. Whether measuring superheat, subcooling, or verifying system pressures during EPA 608 compliance work - you need accurate P-T data in your pocket. This app provides NIST-grade verified saturation tables for all 10 common EPA 608 refrigerants with R-454B transition support.
