Mastercool Electronic Refrigerant Scale 98210-A — Black, 243 lb Capacity & High-Precision

The Mastercool 98210-A ACCU-CHARGE II is a portable electronic refrigerant scale with a 243 lb capacity and high-precision weighing for charging HVACR systems.

Designed for HVAC technicians and refrigeration specialists, this electronic scale combines a durable die-cast platform with a detachable ABS housing to make on-site refrigerant measurement fast and dependable. Its wide 9" x 9" platform accommodates common refrigerant cylinders, and a large backlit display keeps readouts clear in dim workspaces. Built-in charge programming and an audible alarm help manage target fills so you can stop the flow at the correct weight.

How accurate is the ACCU-CHARGE II for everyday refrigerant work?

The scale delivers fine-resolution readings with accuracy suitable for precision charging and service tasks. It consistently holds tight tolerances so technicians can charge systems to specified weights without repeated transfers.

• Accuracy within ±0.05% of reading for precise fills
• Large platform supports standard refrigerant cylinder sizes
• Stable die-cast construction minimizes measurement drift on job sites

How easy is it to use on a crowded job site or in low light?

Portability and legibility are core to the design. The detachable platform and compact case let you move the unit quickly between locations, while the extra-large LCD makes numbers readable from different angles and lighting conditions.

• Removable 9" x 9" platform for convenient placement
• Bold, oversized LCD suited for low-light environments
• Non-slip surface keeps cylinders stable during weighing

What features support accurate charging and avoiding overfill?

The ACCU-CHARGE II includes programmable charge limits and an alarm so you know when the preset quantity is reached. This prevents overcharging and reduces wasted refrigerant by giving you a clear stopping signal before the final ounces pass the valve.

• User-programmable target weights for repeatable charges
• Audible alarm warns before the programmed amount is exceeded
• High-capacity platform up to 243 lb to cover full-size cylinders

What makes the build quality and durability suitable for field use?

Materials and layout were selected for rugged, everyday service. The scale’s core platform is machined from die-cast aluminum for stiffness and longevity, while the ABS housing protects electronics during transport.

• Die-cast aluminum platform resists bending and wear
• Compact case protects the unit while remaining easy to carry
• Non-skid platform finish reduces slippage on uneven surfaces

Who this product is for: The Mastercool 98210-A ACCU-CHARGE II is intended for HVAC technicians, refrigeration service professionals, and facilities maintenance teams who need a reliable, portable refrigerant scale for on-site charging, system servicing, and cylinder verification. If you require precise, repeatable fills, clear readouts in challenging lighting, and a sturdy tool that travels well between service calls, this scale delivers practical features without unnecessary complexity.
