BELEY Digital HVAC Manifold Gauge — Dual Pressure & Temp, 93‑Refrigerant Library, Backlit LCD

BELEY Digital Manifold HVAC Gauge Set is a handheld electronic gauge that measures dual pressures and temperatures, calculates superheat/subcooling, and supports a built‑in database of 93 refrigerants for faster, more accurate HVAC service.

This compact digital manifold replaces bulky analog gauges by combining two simultaneous pressure channels, two temperature probes, and automatic unit conversion into one portable tester. Designed for technicians servicing air conditioners, refrigerators, chillers and cold storage, it gives clear numeric readouts, stores refrigerant properties, and logs leak and vacuum data so you can work faster and with fewer tools.

How does the BELEY manifold display and handle multiple readings?

The unit uses a large backlit LCD and a 32‑bit processor to present pressures and temperatures clearly and update values quickly. It simultaneously shows high and low side pressures plus two temperature inputs so you can calculate operating conditions on the fly.

• Large liquid crystal display with backlight for low‑light work
• Dual pressure channels and dual temperature probe inputs
• Automatic Celsius/Fahrenheit and multi‑unit pressure conversion
• Fast digital sampling with stable readouts for diagnostic confidence

Which refrigerants and calculations does it support?

BELEY’s built‑in refrigerant library covers 93 common and specialty refrigerants so you can select the exact refrigerant type and read corresponding saturation temperatures automatically. The tool also computes superheat and subcooling, and can display vacuum level as a percentage or leak test results.

• Database includes major refrigerants like R134a, R410A, R32, R1234yf, CO2 (R744) and many more
• Automatic pressure‑to‑evaporation temperature conversion for chosen refrigerant
• Superheat and subcooling calculations for charge and troubleshooting
• Vacuum percentage readout and timed leak testing features

What connections, build quality, and durability does the gauge offer?

The manifold uses industry‑standard 1/4‑inch connections and durable valve switches to fit common service hoses and fittings. The housing combines impact‑resistant engineering plastic with a non‑slip silicone coating so it feels solid in hand and resists wear at job sites.

• Standard 1/4-inch ports for universal compatibility with service hoses
• Long‑life valve switches designed for repeated field use
• Rugged plastic shell and silicone grip for drop resistance and comfort
• Quality electronic internals with a high‑precision data acquisition unit

How does it help streamline daily HVAC work?

The combination of multiple simultaneous readings, an internal refrigerant table and fast digital readouts reduces the need for separate thermometers, charts or manual calculations. That saves time during installation, charging, and troubleshooting while improving consistency across jobs.

• Measure pressures and temperatures together to complete checks faster
• Pick refrigerant from the built‑in list to avoid manual lookup errors
• Automatic unit conversions reduce setup time on diverse systems
• Leak timing and vacuum percentage help document service steps

Who is this for? HVAC technicians, refrigeration service professionals, and experienced DIYers who need a single compact instrument to measure both high/low pressures and temperatures while referencing refrigerant properties. It’s suited to routine maintenance, system diagnostics, refrigerant charging and leak/vacuum checks where faster, repeatable digital readings and built‑in refrigerant data streamline the workflow. Note: not intended as a replacement for manufacturer‑specific diagnostic procedures; always follow safety and legal guidelines when handling refrigerants.
