Super Stars HVAC Digital Manifold Gauge for AC Charging — Backlit LCD, Multi‑Refrigerant Support (R134A/R410A/R32)

The Super Stars HVAC Digital Manifold Gauge is a handheld, backlit digital gauge that measures pressure, vacuum, and converts refrigerant pressures into temperatures for accurate AC charging and diagnostics.

Compact and rugged, this multi-refrigerant digital manifold combines precise transducers with a clear LCD backlight and an onboard refrigerant database so technicians can read pressures and corresponding evaporation/condensing temperatures instantly. It supports a broad range of common refrigerants including R134A, R410A, R32, R22, R1234YF and R454B, and adds leak-test and vacuum functions to streamline on-site troubleshooting and charging workflows.

How does this gauge make charging different refrigerants easier?

The built-in NIST refrigerant database automatically converts measured pressures to evaporation or condensation temperatures, eliminating manual lookups or separate charts. This reduces calculation errors and speeds up system charging and diagnosis across many refrigerants.

• Instant pressure-to-temperature conversion for many refrigerants
• Support for R22, R134A, R410A, R32, R404A, R507, R1234YF, R454B and more
• Selectable units (kPa, MPa, bar, PSI) for regional preferences

What measurement accuracy and ranges can I expect on the job?

The gauge uses precision sensors calibrated to deliver reliable readings across a wide span of pressures and vacuums, with a manufacturer-stated accuracy that helps technicians trust their measurements. Both negative pressure (vacuum) and high-pressure readings are covered so a single tool handles leak checks and system charge checks.

• Pressure measurement from -101 to 6000 kPa
• Accuracy specification of approximately ±0.5% FS for consistent results
• Multiple selectable pressure and temperature units for flexible reporting

How do the leak test and vacuum functions improve diagnostics?

Integrated leak-test modes monitor differential pressure and run timers so you can document pressure decay over set intervals, which simplifies locating system leaks. The vacuum measurement mode provides clear vacuum level readouts to confirm evacuation before refilling refrigerant.

• Leak testing with Δp and elapsed-time tracking
• Dedicated vacuum measurement function for evacuation verification
• Automatic power-saving and backlit LCD for low-light work

Is this tool built for field use and safety?

The design prioritizes on-site durability and one-handed operation: a reinforced housing, 1/4" SAE ports, an ergonomic grip and tactile controls make it easy to use with gloves. Battery power and international safety compliance enable safe, portable diagnostics across residential and light-commercial jobs.

• High-strength housing with ergonomic handle for rugged use
• 1/4" SAE ports compatible with common hoses and fittings
• Battery operation, compact footprint, and safety-standard compliance

Who is this for: HVAC technicians, refrigeration specialists and service contractors who need a reliable, portable digital manifold that reduces manual calculations and consolidates pressure, vacuum and leak-testing functions into one tool. It’s well suited to field service, troubleshooting and routine charging of systems using a wide range of modern and legacy refrigerants.
