Duoyi HVAC Digital Manifold Gauge Set 89 Refrigerants Pressure Leak Vacuum Test Temp Clamps Hoses 0-6000 kPa Plastic

Duoyi Digital Manifold Gauge Set helps you install, test, and fix air conditioners, fridges, and cold storage units. It reads two pressures and two temperatures at the same time. It also switches pressure units and °C/°F automatically. There are 89 refrigerants stored inside, so it shows saturation temperature and figures out subcooling and superheat for you. You can run a pressure leak test by comparing two readings. The large screen has a backlight for dark places. It comes with 1/4 inch ports and long‑lasting valves. The 32‑bit processor keeps readings steady. Hoses and temperature clamps are included. The warranty lasts 12 months.

• See Both Pressures and Temperatures at the Same Time:The screen shows high side pressure, low side pressure, evaporation temperature, and condensing temperature together. Pressure units include kPa, MPa, bar, inHg, and PSI. Temperature switches between °C and °F with one button. No manual conversion needed.You don't need to flip through different screens or modes to get all the numbers.
• 89 Refrigerants Stored Inside:Built‑in data for 89 refrigerants including R134A, R410A, R32, and R1234yf. Just pick the one you are using, and the gauge gives you saturation temperature, subcooling, and superheat automatically.
• Pressure Leak Test by Comparing Two Readings:Record the first pressure reading, wait, then take a second reading. The gauge shows the difference between them, helping you tell if the system is losing refrigerant.
• Easy to Read and Stable:A 32‑bit processor and accurate sensor give steady readings. The large backlit screen works well even in dim light or at night.
• Standard Fittings with Durable Valves:Uses 1/4 inch standard ports and long‑lasting valve switches. Fits most AC service connections and stays reliable through many uses.
