Fieldpiece SM482V Wireless 4-Port SMAN Refrigerant Manifold with Vacuum Gauge – Air

The Fieldpiece SM482V is a wireless four-port digital refrigerant manifold designed for HVAC and refrigeration technicians handling diagnostic, evacuation, and charging tasks. It combines digital pressure measurement with an integrated micron vacuum gauge, giving technicians a consolidated platform to service cooling equipment without switching between separate tools.

This four-valve unit accurately measures both low-side and high-side pressures while automatically calculating superheat and subcooling values. It features protected thermocouple jacks to capture pipe and outdoor temperatures directly, and it includes the ability to connect with Job Link Psychrometer probes. In addition, onboard data logging helps track performance over time, while a temperature-compensated tightness testing function aids in confirming system integrity during pressure checks.

While the manifold offers extensive digital diagnostics, the product listing does not state specific physical dimensions, overall weight, battery requirements, or screen size. Buyers should also note that external psychrometer probes are mentioned as compatible accessories rather than included items in the box.

Verdict: The Fieldpiece SM482V is well suited for HVAC and refrigeration professionals who want a four-valve digital manifold with built-in vacuum tracking and data logging. It provides a comprehensive diagnostic setup for complex system maintenance and leak testing.

A great fit if you:

• Need a four-port manifold that integrates vacuum and micron tracking into one device
• Require real-time calculations for superheat and subcooling on service calls
• Want to run temperature-compensated tightness tests and log diagnostic data
• Plan to connect external Job Link psychrometer probes for extended airflow readings

Consider something else if you:

• Prefer a simple analog manifold without digital readouts or data logging
• Only need basic two-port gauges for quick residential checks
