Eliminate the hassle of switching between multiple devices during AC charging, system evaluations, or maintenance checks. This all-in-one solution streamlines workflows, enabling faster refrigerant leak detection, deep vacuum pulls, and performance assessments. Whether you’re troubleshooting residential units or commercial systems, this gauge set ensures efficiency and accuracy for every task.

Universal Compatibility with 22 Refrigerants

Engineered for versatility, this HVAC gauge features a built-in NIST-certified database compatible with 22 refrigerants, including R12, R22, R134A, R410A, R502, R1234yf, and other common and next-gen refrigerants like R32, R404A, R507, and R600. Designed for AC charging, diagnostics, and recovery, it adapts seamlessly to diverse HVAC/R systems, making it indispensable for professionals handling residential, automotive, or industrial applications.

Precision Performance with Advanced Technology

Equipped with a 32-bit digital processor and high-precision data acquisition, this gauge delivers ±0.5% (FS) accuracy across an expansive pressure range of -101kPa to 6000kPa. The dedicated vacuum measurement range (-101kPa–0kPa) ensures reliable diagnostics for evacuation tasks. Backed by robust engineering, it provides consistent, repeatable results for critical HVAC operations, from system charging to post-repair verification.

Ergonomic Design Built for Durability and Clarity

Crafted from high-quality impact-resistant plastic and non-slip silicone, this gauge set offers a comfortable grip and long-lasting durability. The large backlit LCD screen ensures crystal-clear visibility in low-light environments, while the multi-unit display (kPa, MPa, bar, inHg, PSI, Kgf/cm²) and °C/°F temperature readings simplify operation in any setting. Additional features like a visual mirror design, US-standard threads, and 1/4" quick-connect inlets enable effortless installation and compatibility with standard HVAC tools.
