VIVOHOME HVAC Refrigerant Scale RCS-320V — 220 lb Capacity, Auto-Dosing Solenoid Valve, ±0.05% Accuracy

The VIVOHOME RCS-320V HVAC refrigerant scale is a digital charging and recovery scale with an independent solenoid auto-dosing valve that delivers ±0.05% rdg+10 g accuracy to prevent overcharging and speed refrigerant service.

Designed for HVAC/R technicians who need repeatable, hands-free refrigerant management, the RCS-320V pairs a heavy-duty aluminum weighing platform with a digital keypad and remote control. It supports up to 220 lb capacity, shows weights in kg/lb/oz, and lets you open or close the dedicated solenoid valve to remove air or stop flow at a preset weight. The combination of automated shutoff and clear alerts reduces guesswork during charging and recovery tasks.

How does the auto-dosing solenoid valve improve charging accuracy?

The RCS-320V’s built-in solenoid valve can be closed automatically when the preset weight is reached, eliminating manual intervention and human timing errors. This prevents overcharge and ensures consistent fills across multiple service calls.

• Solenoid-controlled shutoff at target weight for precise dosing
• Independent manual control via keypad to purge air before charging
• Hook design for convenient valve placement and connection

What measurement features and controls will I use in the field?

A bright LCD, full digital keypad, and remote display make the scale easy to operate in dimly lit equipment rooms. You can program capacities up to 220 lb, switch display modes among kg, lb, and oz, and receive alarms for preset limits or full-load conditions.

• Three display modes (kg/lb/oz) for flexible reporting
• Preset capacity programming and audible/visual alerts
• Automatic power-off and battery-level indication on the remote

How durable and service-ready is the scale for daily HVAC work?

Built around a thick-walled aluminum frame, the RCS-320V withstands regular workshop or field use while keeping readings stable. Rubber feet and pads absorb shocks, and the solid construction protects the load cell and electronics during transport and operation.

• Heavy-duty aluminum housing for long-term accuracy
• Rubber feet and pads to reduce impact and vibration
• Rugged solenoid valve and accessible controls for fast service

Which refrigerants and applications does this scale support?

The RCS-320V is compatible with all common refrigerants, making it suitable for residential systems, commercial HVAC units, and automotive air-conditioning service. Its capacity and accuracy make it useful for both small service calls and large-scale maintenance tasks.

• Compatible with R-134a, R-410A, R-22 replacements, and other refrigerants
• Useful for home AC, rooftop units, cold rooms, and vehicle A/C
• Accurate for both charging and recovery operations

Who is this for: The VIVOHOME RCS-320V is aimed at HVAC/R professionals, service contractors, and mobile technicians who need a dependable, repeatable charging solution that reduces manual monitoring and improves job consistency. If you handle refrigerant charging or recovery regularly and want to cut downtime while improving accuracy, this scale delivers a durable, feature-rich tool for field or shop use.
