VIVOHOME VH104 Refrigerant Scale, 220 lb Capacity with Backlit LCD

For HVAC refrigerant charging, the VIVOHOME VH104 lets you weigh a cylinder as you transfer refrigerant, helping you track the amount added rather than relying on guesswork.

Its 220 lb capacity and selectable kg, lb and oz display formats make it practical for different weighing preferences. The backlit LCD keeps the reading visible in varied work areas.

A hard carrying case protects the scale during transport, while the aluminium platform with a textured silicone surface helps keep a tank from slipping during measurement.

What you’ll notice day to day

The VH104 is designed for technicians who need a portable scale for refrigerant recovery and charging work in places such as a workshop, factory or warehouse. Its compact format and carrying case make it straightforward to move between jobs, and the platform’s grippy surface supports steadier cylinder placement while you monitor weight.

Choose between kg, lb, oz, kg and g, or lb and oz to read measurements in a format that suits your workflow. The auto-zero button lets you set the display to zero after weighing the cylinder, which helps track the refrigerant added separately from the cylinder’s weight. A 5 g resolution and stated accuracy of ±0.05% of the reading plus 10 g provide useful detail when managing a charge by weight.

Customer feedback often highlights accurate readings, easy operation and effective performance during refrigerant transfer. Some users also mention battery-management concerns, and durability feedback is mixed. The scale operates on a 9V battery, which is not included.

Key takeaways

The large LCD has a backlight for easier reading, and the scale is built from aluminium and silicone. It also includes overload detection: when a load exceeds the specified range, the display shows “FULL”. For technicians comparing a basic, non-portable weighing setup with a dedicated refrigerant scale, the VH104 brings measurement, transport and tank stability features together in one tool. What helps when the cylinder weight needs to be separated from the refrigerant charge? The auto-zero function provides a direct way to reset the reading after weighing the cylinder.

Power-saving shutoffs are built in: the scale turns off after 10 minutes without use, and the backlight switches off after 3 minutes of inactivity. If power is lost because of low battery voltage or the scale is turned off, the fail-safe design is intended to close the valve.

How to use it

Place the refrigerant cylinder securely on the platform, then use the display and auto-zero control to track the charge by weight. Keep the cylinder centred on the textured surface while taking a reading. Select the preferred units from the available display modes, and use the backlit LCD to check measurements as work progresses. The scale is powered by one 9V battery, the carrying case helps keep the equipment together between jobs.

Buying verdict

A solid pick if you need a portable refrigerant charging scale with a 220 lb capacity, a readable backlit display and controls for tracking weight during HVAC work. Its multiple unit modes, auto-zero function, non-slip platform and hard case make it a practical fit for technicians who move between charging or recovery tasks and want a dedicated scale that is easy to carry and use.
