Connectable to mobile devices via the Hi VALUE App, the system works together with the VRS2A smart scale to automatically complete refrigerant weighing. Compatible with A2L refrigerants, it allows easy and effortless charging and recovery operations. Three indicator lights show real-time operating status (flow, Bluetooth connection, and power), providing instant control at a glance. The overload protection system automatically stops the flow when the weight exceeds the allowed limit. The high-strength rubber and plastic housing is designed to resist impacts, ensuring durability and long service life. The compact design with integrated hook makes transport and field use easy. The lithium battery provides up to 60 hours of autonomy, while the USB-C port allows fast and eco-friendly charging. Bluetooth connection range: 30 meters.
