Hilmor RSW220 Wired Refrigerant Scale (100 kg / 220 lb) delivers accurate, stable weighing for charging and recovery. Read in fine 0.2 oz (≈5 g) increments on a backlit display, with a rubberised platform that keeps cylinders planted. Use it in or out of the case — too easy on rooftops and in tight plant rooms.

Key Features & Trade Benefits

• 100 kg capacity — covers everyday bottles through to heavier recovery jobs without juggling scales.
• Fine resolution — 0.2 oz / 5 g steps for precise charging and recovery → fewer call-backs.
• Backlit, easy-read LCD — clear numbers in bright sun or dim plant rooms; get it right first time.
• Rugged & versatile — works in or out of the protective case for extra weather protection on site.
• Stable platform — rubberised surface grips the tank and protects the deck; less wobble, safer work.
• Field-ready power — 5 × AAA cells, up to ~40 hours runtime to get through big days.

Why this scale matters

Real-world: on a 40-degree Sydney roof the cylinder was sweating, and guesswork would’ve ended in an overcharge. The RSW220 sat in its case, rock-steady, letting us meter in the last few hundred grams while the backlit handheld stayed legible — fair dinkum time saver. Weighing refrigerant is also good practice for compliance and best-practice charging per Australian industry guidance.

Pro Tip

Tare with the empty cylinder and valve first, then log the net charge as you go. For recovery, track bottle weight rise to avoid overfilling — and keep the scale in its case when conditions are sketchy. No worries.
