Fieldpiece SMAN 482V Digital Manifold

The Fieldpiece SMAN 482V is a well-thought-out evolution of the digital manifold. It is not a reinvention, but a refinement of tools and workflows technicians already rely on. Nothing about this manifold feels gimmicky. Instead, its design makes proven best practices easier to execute consistently in the field.

Features like the built-in micron gauge and 3/8-in. vacuum ports aren’t new concepts, but their integration matters. Having vacuum measurements built directly into the manifold simplifies setup, reduces extra connections, and supports cleaner evacuations and recovery when paired with proper hose practices.

The workflows encourage technicians to verify evacuation quality rather than assume the job is done.

The SMAN 482V also shines during pressure testing. Its temperature-compensated nitrogen pressure test helps account for ambient temperature changes, reducing false pressure drops that can lead to unnecessary troubleshooting or callbacks. That’s a confidence builder feature that saves time and frustration, especially on longer tests.

From a durability standpoint, this tool is ready for real job-site conditions. The construction is rugged and water-resistant, valves are solid and durable, and buttons are easy to use — even with gloves. The display is clean and readable, without overwhelming the user with clutter.

Where the SMAN 482V shines is in its connectivity. Data logging allows technicians to track refrigerant performance over time, and integration with JobLink system tools pulls pressure, temperature, airflow, and refrigerant scales into one place. That makes diagnostics clearer, documentation easier, and decisions more confident.

Overall, the SMAN 482V isn’t about flashy upgrades; it’s about supporting accurate diagnostics and professional-level work. Learn more at the Fieldpiece website.
