Advanced digital refrigerant manifold & vacuum gauge

The Fieldpiece SM480V is a wireless four-port SMAN manifold designed for HVAC and refrigeration technicians who need accurate pressure, temperature, superheat and subcooling measurements during diagnostics and service. It combines a micron gauge with data logging and a system tightness test in a single rugged instrument.

Replaces analog gauge sets

Upgrading is worthwhile when a technician requires continuous data logging for up to 168 hours, wireless probe connectivity for psychrometric readings, and a built-in tightness test to verify leak-free repairs without separate tools. The IP54-rated casing and impact-resistant screen withstand daily job-site abuse.

Practical limits of the wireless SMAN platform

Internal storage holds only nine jobs, so longer projects need frequent offloading. Wireless range and battery life depend on site conditions and probe usage, and the four-port block limits simultaneous connections to four hoses. The tool is not suited for automotive A/C work requiring different refrigerant scales or fittings.

Questions about this item

What hose connections does the four-port manifold accept?

The SM480V has four valve ports for standard refrigerant hoses and protected thermocouple jacks for pipe and outdoor temperature probes.

How do you start a data-logging session, and what step is often missed?

Power on the unit, select a job slot, then press the log button; the step often missed is confirming the 168-hour capacity before beginning.

When should the vacuum sensor be checked for accuracy?

Verify the micron gauge against a known reference before each evacuation job and after any drop or impact to the IP54-rated housing.
