Precision HVAC Charging Scale

The Metra refrigerant charging scale measures cylinder weight up to 220 lbs with a resolution of 5 g and stated accuracy of ±0.05% reading plus 10 g. Technicians charging air-conditioning or refrigeration systems use it to verify the exact mass of refrigerant added or recovered.

Portable Platform with Carrying Case

The aluminium and silicone platform measures 32.2 cm wide by 45.1 cm deep and stands 7.4 cm high, weighing 3.55 kg. A hard carrying case protects the unit during transport. The scale runs on a single 9 V battery (not supplied) and offers three display modes for kg, lb, oz and combined units.

Auto-Shutoff and Overload Protection

The backlight extinguishes after three minutes of inactivity and the unit powers down completely after ten minutes. An auto-zero button lets the operator tare the cylinder weight before charging. If the load exceeds 220 lbs the display shows "FULL" and a fail-safe valve closes automatically should power be lost.
