VIVOHOME Refrigerant Scale 220 lb HVAC Digital Portable — Backlit LCD, High-Precision

The VIVOHOME 220 lbs High Precision Electronic Refrigerant Scale is a portable digital HVAC scale designed for accurate refrigerant charging, tank weighing, and on-site HVAC service work.

Compact yet robust, this digital refrigerant scale from VIVOHOME combines a high-visibility backlit LCD, a textured non-slip platform and a durable aluminum-silicone deck to deliver reliable measurements up to 220 pounds. It runs on a single 9V battery, stores the last reading if power is lost, and includes multiple weight units and an auto-zero function to simplify refrigerant transfer and cylinder management.

How precise and reliable is this scale for HVAC refrigerant charging?

The scale is engineered for professional use with high-accuracy electronics and a large LCD display that shows measurements clearly in kg, lbs, oz, or combined units. Features such as auto-zero, data retention on power loss, and an over-load "FULL" indicator reduce risk of inaccurate readings during long jobs.

• 220 lb (100 kg) maximum capacity with high-precision sensors
• Auto-zero button to tare cylinder weight before charging
• Overload “FULL” alert prevents readings beyond range
• Stores last weight after auto-shutoff or power interruption

What makes this scale easy to use on the job site?

The scale’s compact footprint, lightweight construction and hard carrying case make it convenient to transport between jobs. The backlit, easy-to-read LCD and simple control buttons let technicians read and switch units quickly in dimly lit mechanical rooms.

• Compact, portable design powered by one 9V battery (not included)
• Large backlit LCD for low-light visibility
• Multiple unit modes: kg, lbs, oz, kg&g, lbs&oz
• Hard carrying case included for protection and storage

How does the scale keep cylinders steady and safe while weighing?

A textured rubber coating combined with an aluminum frame increases traction and reduces slippage during measurement. The non-slip platform helps prevent tanks from shifting or falling while technicians perform refill or evacuation tasks.

• Aluminum body plus silicone/rubber coating for high traction
• Textured platform surface secures cylinders during weighing
• Stable base minimizes measurement errors from movement
• Auto-shutoff after 10 minutes conserves battery life

What safety and fail-safe features are included to protect measurements?

The scale includes multiple safeguards: an overload indicator, auto-shutoff to preserve battery life, and a memory function that retains the last measured weight if power is interrupted. These prevent data loss and help maintain accurate records across multi-step charging jobs.

• Displays “FULL” when weight exceeds the 220 lb limit
• Auto-shutoff after 10 minutes of inactivity; backlight off after 3 minutes
• Last weight saved automatically if power is lost
• Simple controls reduce operator error during recalibration

Who is this for? HVAC technicians, refrigeration service professionals, facilities maintenance staff, and any contractor who needs a portable, precise refrigerant charging scale will benefit from the VIVOHOME 220 lbs High Precision Electronic Digital Refrigerant Scale. It’s especially useful where compact transport, clear low-light readings, accurate tare functions and fail-safe data retention are required on the job.
