Super Stars HVAC Digital Manifold Gauge for AC Charging — Backlit LCD, Multi‑Refrigerant, ±0.5% Accuracy

Super Stars HVAC Digital Manifold Gauge is a backlit, multi‑refrigerant diagnostic tool that measures pressure, vacuum and temperature equivalents for accurate AC charging and leak testing on professional systems.

This compact digital manifold combines a clear LCD backlight, a built‑in refrigerant database and precision sensors to speed up routine HVAC service calls. It supports a wide range of refrigerants — including R134A, R410A, R32, R22 and newer blends like R1234YF and R454B — and converts pressure values to evaporation or condensation temperatures so you can interpret system conditions without manual lookups. Lightweight and battery powered, the unit is built for field use with 1/4" SAE ports and simple one‑hand controls.

How accurately does it read pressure and vacuum?

The Super Stars gauge delivers laboratory‑grade readings across its full span with ±0.5% FS accuracy. It measures from -101 kPa (vacuum) up to 6000 kPa (high pressure) and offers multiple display units so you can work in kPa, MPa, bar or psi. Fast sampling and a backlit screen keep values readable in dim workspaces.

• Accuracy: ±0.5% full scale for consistent diagnostics
• Range: -101 to 6000 kPa covers most HVAC/R systems
• Units: selectable kPa, MPa, bar, PSI and more
• Visibility: LCD backlight for low‑light jobs

Which refrigerants and features help with charging and system checks?

The built‑in NIST refrigerant database automatically converts measured pressures to their corresponding saturation temperatures for dozens of refrigerants. That removes manual reference charts during charging and troubleshooting. The gauge also includes leak testing modes and a timer function to capture differential pressure changes.

• Refrigerant support: R22, R134A, R410A, R32, R404A, R507, R1234YF, R454B and more
• Temperature conversion: pressure → evaporation/condensation temperatures
• Leak testing: Δp and timed measurements to detect slow losses
• Convenience: instant conversions speed charging and diagnostics

Is the gauge durable and easy to use in the field?

Yes — the housing is built from reinforced materials to withstand drops and onsite handling, while the button layout and ergonomic grip allow single‑hand operation. Standard 1/4" SAE ports accept common hoses and fittings, and the unit runs on batteries for off‑grid work. Auto power‑save extends battery life between jobs.

• Construction: high‑strength casing resists field wear
• Ports: 1/4" SAE for universal hose compatibility
• Operation: ergonomic design for one‑hand control
• Power: battery operation plus auto power‑saving feature

How does it support safety and portability on service calls?

The Super Stars digital manifold meets international safety standards and is sized for easy transport in a technician’s kit. Its compact footprint and lightweight design mean you can take it to tight equipment rooms, and the backlit display ensures readings are clear without external lighting.

• Compliance: built to recognized safety specifications
• Portability: compact, lightweight for on‑site diagnostics
• Visibility: backlit LCD to work in low‑light areas
• Battery powered: no mains required for remote service

Who is this for? HVAC technicians, refrigeration specialists and facilities maintenance teams who need a fast, accurate handheld manifold for multi‑refrigerant systems will benefit from this tool. It’s designed for professionals who perform charging, leak checks and routine diagnostics across different refrigerants and need a durable, easy‑to‑read instrument that reduces guesswork and reference lookups on the job.
