Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 12 November 2026). Where a listing contradicts itself, each stated figure is shown.

How the scores work

Each scale earns a Shop Score from performance, build, value, safety and warranty, weighted as published on the How We Pick page. No listing states a UL, ETL or CSA listing, so every scale scores zero on safety, and the listings with no warranty term score zero on warranty.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

5 scale listings were compared. 3 stated a 2 g resolution and 2 stated 5 g. 3 stated a 1 year warranty and 2 stated no warranty term. 2 scales stated a 220 lb capacity and 3 stated 110 lb. 1 scale stated a temperature range, and 1 stated that it saves the last entered weight when power is lost.

Buying guide: the best electronic refrigerant charging scale for your garage

Capacity

A 110 lb scale covers the recovery tanks most home garages use, while a 220 lb scale suits larger tanks. Match the capacity to the tank that will sit on the platform, and leave headroom so the scale never reads FULL mid-charge.

Resolution and accuracy

Resolution is the smallest change the display shows: 2 g against 5 g here. Accuracy is stated as 0.05% of the reading, with a fixed amount of 5 g on one 110 lb scale and 10 g on the 220 lb scales. Finer resolution and a smaller fixed amount suit small charges, where each gram counts.

Display and controls

A backlit LCD with a bracket that tilts to 110° reads well in dim light, and a remote or removable control box keeps the display where it can be seen. Display modes cover g, Kg, Oz and Lb, with some scales adding combined modes. An auto-zero control sets the reading to zero after the cylinder weight is measured.

Battery and shut-off

Every scale here runs on a 9V battery. One listing includes the battery and states up to 40 hours, one states over 30 hours, and one states the battery is not included. Every scale shuts off after 10 minutes without use, and the backlight switches off after 10 seconds or 3 minutes, depending on the listing.

Case and platform

A hard case keeps the scale safe in transit and in storage, and a 9 in x 9 in platform with a non-slip pad keeps the tank from sliding. The VIVOHOME measures 17.0 in x 12.0 in x 3.0 in, the largest footprint here, while the Robinair control box lifts off the platform on a prop stand or hanging hook.

Garage Fit Check

• Measure the bench or floor space for the platform: 9 in x 9 in on three scales, 17.0 in x 12.0 in on the VIVOHOME.
• Keep a spare 9V battery on hand, since one listing states the battery is not included.
• Store the scale in its hard case between jobs, with the platform clear of tanks and tools.
• Check the capacity against the recovery tank before the first charge, so the scale never reads FULL mid-charge.
• Work in the stated temperature range: 32°F to 122°F on the VIVOHOME.

FAQ: garage tools

Do AC units need refrigerant?

Yes, an AC system needs refrigerant to move heat. When cooling fades, low refrigerant is one cause, and a charging scale weighs the refrigerant as it goes in so the charge matches what the maker lists.

How to check refrigerant in an AC unit?

Weigh the charge with a refrigerant charging scale: set the recovery tank on the platform, zero the display, and watch the weight change as refrigerant moves. The scale shows the weight in g, Kg, Oz or Lb.

How to refill AC refrigerant?

Connect the recovery tank, set the tank on the scale, zero the display, and add refrigerant until the scale shows the weight the system maker lists. Refrigerant handling is regulated, so a licensed technician should do the work where the rules require it.

How to remove refrigerant from an AC system?

Recovery means moving refrigerant from the system into a recovery tank on a charging scale, so the weight removed is known. The tank must stay within the scale capacity, and recovered refrigerant goes to a licensed handler.

How much is refrigerant for an AC unit?

The listings compared here state no refrigerant price, and the amount a system needs varies by system. A charging scale shows the weight added, so the charge can be matched to what the system maker lists.
