<h3>Key features</h3><ul> <li>3-in-1 Digital HVAC Manifold Gauge Set Combines pressure test, vacuum measurement, and pressure leak test with delta-P tracking into one tool. The large backlit LCD displays real-time pressure, pressure drop over time, and elapsed test duration simultaneously — no more switching between gauges or reconnecting hoses.</li> <li>Built-In 24 Refrigerant Database Instantly read saturation temperatures for R1234yf, R134A, R410A, R22, R32, R404A, R507, and more — based on NIST standards. Easily obtain both evaporation and condensation temperature</li> <li>Precision for Pros &amp; Accessible for DIY 32-bit processor delivers ≤±0.5% full-scale accuracy with a fine 1 kPa pressure step, capturing even the slightest pressure changes. Dedicated vacuum and pressure leak test modes make one-person system diagnostics straightforward — ideal for DIY homeowners and auto enthusiasts.</li> <li>Rugged Build &amp; Field-Ready Design High-strength engineering plastic housing with a non-slip silicone grip and heavy-duty metal valve block handles daily jobsite wear. Auto-off after 15 minutes conserves battery, while the backlit display stays awake during leak tests for uninterrupted monitoring.</li> <li>Pressure range:101 kPa – 6,000 kPa; 10 MPa overload protection (100 bar). Standard hose max working pressure: 600 PSI (≈206.8 bar). Supports 6 units: kPa, MPa, bar, inHg, PSI, kgf/cm².</li> </ul><p>Free shipping on orders $50+. 30-day hassle-free returns.</p>
