Dual Digital HVAC Manifold Gauges: Traditional analog manifolds slow with manual conversions and PT chart lookups. The dual digital manifold gauge provides fast pressure readings and temperature reference after refrigerant selection—so you can charge and diagnose with confidence and consistency
94 Refrigerants Built-In: Supports 94 refrigerants including R454B, R32, R1234yf, R410A, R134a, R22 and more. One tool covers a wide range of HVAC and auto AC systems—reducing the need to carry multiple gauges
High Accuracy: This digital ac gauge delivers stable, dependable measurements with an accuracy of ±0.5% FS, helping support HVAC system diagnostics, commissioning, and routine maintenance without the guesswork
Multi-Unit Readings And Vacuum Test: Display pressure in kPa, mbar, bar, inHg, and psi, and switch temperature units between ℉ and ℃. Supports vacuum pressure checks for evacuation verification and basic diagnostics
Large LED with Sight Glass: 3-port manifold layout with a color LED display plus an integrated sight glass to visually confirm refrigerant flow during charging. Practical features like auto shut-off help extend battery life for dependable everyday use
