Aain A36575 Refrigerant Scale HVAC Digital Charging Weight Scale

In this review the Aain A36575 Refrigerant Scale is evaluated as a practical tool for HVAC technicians and service shops who need a portable, accurate way to charge or recover refrigerant. The bottom line: this scale stands out for its 220 lb capacity and large, backlit LCD which makes weighing refrigerant cylinders straightforward on the job. The unit's durable construction and included carrying case mean it is designed for regular field use, and the automatic charging/recovery capability simplifies transfer work directly between tank and system.

Key Features

• 220 lb capacity: The high load capacity handles full-size refrigerant cylinders so technicians can charge or recover without switching containers.
• Extra large LCD: The prominent backlit display provides clear readings in dimly lit service areas and the backlight times out to save battery.
• Slip-resistant platform: The 9' x 9' weighing surface keeps cylinders stable during transfer to reduce the risk of drops or shifting.
• Universal refrigerant use: The scale is compatible with all common refrigerants, allowing direct charge or recover work across systems.
• Portable design: Rugged plastic and metal construction plus a heavy duty carrying case make it easy to transport between job sites.
• Multiple units and alarm: Switchable readouts in kg, oz, and lb and a built-in alarm warn when capacity or preset limits are exceeded.

Who It's For

This scale is aimed at HVAC technicians, service contractors, and shop owners who perform regular refrigerant charging and recovery and need a portable, durable solution that handles the full-size tanks. The automatic charging/recovery function and universal refrigerant compatibility make it especially useful for mixed-fleet work where technicians service many different systems.

It is less suited to users who only occasionally handle very small cans or who require laboratory-grade precision beyond typical field accuracy. If you need integrated software logging or vehicle-mounted permanent scales, look for specialized equipment with those features.

Pros & Cons

Pros

• High 220 lb capacity lets you weigh and charge common refrigerant cylinders without swaps.
• Large backlit LCD improves legibility in low light and quick readings on site.
• Sturdy, compact build with a slip-resistant 9' x 9' platform and included carrying case for real portability.

Cons

• Auto-shutoff and backlight timeout can interrupt long sessions if batteries are not monitored.
• No built-in data logging or wireless connectivity for digital record keeping.
