SM482V, 4-Port SMAN Digital Refrigerant Manifold w/ Micron Gauge

Fieldpiece SM482V 4-Port SMAN Digital Refrigerant Manifold with Micron Gauge

The Fieldpiece SM482V is a 4-port digital manifold that combines refrigerant charging, recovery, and deep vacuum measurement in one tool. Built with an integrated micron gauge, it lets HVAC techs confirm evacuation quality without swapping tools or losing time. The 4-port design dedicates separate ports for vacuum and charging, so you can pull refrigerant and prep for the next step simultaneously. This manifold calculates superheat and subcooling, logs data, and connects wirelessly to the Job Link system when paired with compatible probes, giving you the diagnostic power and reporting speed that modern service work demands.

Key Features & Benefits

• 4-Port Configuration: High, low, vacuum, and charge ports eliminate hose swapping during recovery and charging. You finish jobs faster because the manifold handles multiple tasks at once without reconnecting lines.
• Built-In Micron Gauge: Measures vacuum levels directly on the manifold body to confirm deep vacuum during evacuation. You know the system is ready for refrigerant without attaching a separate gauge.
• Superheat and Subcooling Calculations: Automatically calculates these values when temperature inputs are provided. You diagnose charge levels and airflow issues accurately without manual math.
• Data Logging: Stores readings and job parameters for later review. You can document system conditions and share reports with customers or service managers.
• Job Link System Compatibility: Pairs wirelessly with Fieldpiece probes to display live data and generate reports. You work hands-free and capture readings from across the system in real time.
• Robust Construction and Sealed Electronics: Designed to withstand jobsite conditions from 14°F to 122°F at humidity levels below 75%. Your investment lasts through years of van transport and outdoor installations.
• 405-Hour Battery Life: Runs on six AA alkaline batteries for extended field use. You complete multiple service calls on a single set of batteries without scrambling for spares.

Compatibility & Requirements

The SM482V works with the full refrigerant library programmed into Fieldpiece SMAN manifolds. It requires six AA alkaline batteries, which are included. The manifold integrates with the Fieldpiece Job Link wireless system when you add compatible temperature and pressure probes (sold separately). The manifold replaces the earlier SM480V model and uses the same hose holders and pipe clamp accessories.

Frequently Asked Questions

Q: What is the battery life of the Fieldpiece SM482V?

A: The SM482V runs for 405 hours on six AA alkaline batteries. Battery life varies based on how often you activate the backlight and wireless features, but this runtime covers weeks of typical service calls before you need replacements. The manifold ships with batteries installed.

Q: How does the micron gauge work on the SM482V?

A: The micron gauge is built into the manifold body and measures vacuum levels directly during system evacuation. You connect your vacuum pump to the dedicated vacuum port, start the pump, and watch the micron reading drop on the display. When the reading holds steady below your target (commonly 500 microns or lower), the system is dry and ready for refrigerant. No separate micron gauge or additional hose connections are required.
