VIVOHOME Refrigerant Charging Scale 220 lb — High-Precision HVAC Digital Scale with Backlit LCD and Auto-Tare

VIVOHOME 220 LBS High Precision Electronic Refrigerant Scale is a portable HVAC charging scale that measures up to 220 pounds with a bright LCD, non-slip platform, and auto-save fail-safe features.

This compact, battery-powered scale is built for technicians who need accurate refrigerant and cylinder weight readings on the job. Its large backlit display, auto-zero capability, and multiple measurement modes (kg, lbs, oz combinations) make it a reliable tool for charging, reclaiming, and servicing HVAC systems. Housed in a protective hard case and designed with traction surfaces, the scale balances precise electronics with rugged field-ready practicality.

How does this scale deliver accurate readings during refrigerant charging?

The VIVOHOME scale uses a high-precision sensor and supports an auto-zero function so you can tare the platform after placing an empty cylinder. A large, high-visibility LCD and selectable units prevent misreads, while the unit stores the last weight if power is lost, reducing measurement interruptions.

• High-precision load cell calibrated for consistent readings
• Auto-zero (tare) to subtract cylinder tare weight quickly
• Multiple display modes: kg, lbs, oz, kg&g, lbs&oz
• Auto-save of the last weight if power is interrupted

What features make it durable and field-ready for HVAC work?

The scale blends an aluminum frame with a textured silicone/rubber surface to prevent slippage from refrigerant cylinders and tanks. A rugged hard carrying case protects the unit during transport, and the design includes an auto-shutoff to conserve battery life while keeping performance reliable in varied jobsite conditions.

• Aluminum construction with silicone-coated platform for traction
• Hard carrying case for protection and convenient storage
• Auto-shutoff after 10 minutes, backlight off after 3 minutes
• Displays “FULL” when capacity exceeds 220 lbs to prevent overload

How easy is it to operate and read in low-light or busy environments?

Operation is straightforward: place the cylinder, use the auto-zero button to tare, then read the large backlit LCD. The backlight improves visibility in dim spaces and the simple button layout keeps single-handed operation possible while handling cylinders or gauges.

• Large, backlit LCD for clear readings in low light
• Simple button controls for unit selection and tare/reset
• Operates on a single 9V battery (not included) for true portability
• Three display durations and a fail-safe last-weight memory

What safety and over-load protections are included?

The scale prevents user confusion and equipment stress with a visible overload indicator and auto-save memory. If a load exceeds the rated 220 lb capacity, the display reads “FULL,” and the unit will not accept weights beyond that limit, helping technicians avoid sensor damage.

• Overload indicator displays “FULL” when capacity is exceeded
• Auto-save stores last weight in case of shutoff or battery change
• Auto-backlight and auto-shutoff reduce risk of battery drain mid-job

Who is this for: HVAC technicians, refrigeration specialists, contractors, and service professionals who need a portable, accurate charging scale for refrigerant cylinders and tanks. It’s ideal for fieldwork where durability, clear readings, and quick tare functions matter most.
