Portable HVAC Refrigerant Scale

The Metra 110 lb digital charging scale provides precise refrigerant weight measurements for HVAC technicians and installers. It offers a 110 lb capacity with 5g resolution and accuracy within ± 0.05% rdg + 5 g. Five unit options include kg, lbs, oz, kg & g, and lbs & oz for flexible readings.

Verify Cylinder Weight and Temperature Range

Confirm your refrigerant cylinders fall within the 110 lb maximum capacity before ordering. The operating temperature range spans 14 °F to 104 °F, while storage tolerates 5 °F to 122 °F. Ensure the job site environment stays within these limits for reliable sensor performance.

Battery Life and Auto-Off Behaviour

The scale enters an energy-saving mode and powers off after 10 minutes of inactivity to preserve battery life. Pressing both the LAMP and UNIT buttons simultaneously disables this automatic shut-off for continuous monitoring. A carrying case protects the 3.6 kg unit during transport and storage.

Questions about this item

Does the package include the refrigerant cylinder or just the scale, case and manual?

The box contains the refrigerant charging scale, a carrying case and an instruction manual; no cylinder or refrigerant is included.

Should I choose the 110 lb model or a higher-capacity version for typical residential HVAC work?

The 110 lb (50 kg) capacity covers standard residential refrigerant cylinders, while heavier commercial tanks may need a 220 lb (100 kg) model.

What does the ±0.05% plus 5 g accuracy mean when weighing a 10 kg charge?

At 10 kg the maximum deviation is ±10 g, giving confidence for precise refrigerant charging.
