Why This Product Matters

Ever been up on a 40-degree roof chasing a “warm fridge” complaint? We set the 98201 under the cylinder, tared it, and charged by weight — system pulled in exactly what the nameplate called for and the head pressure settled. Bloody good way to prevent over/under-charging and the inevitable call-back. For more gear, see our Digital Scales collection.

Pro Tip

Always tare the cylinder and hose set before you open the manifold. Log “out” and “in” weights for warranty notes. When working with A2L refrigerants (e.g., R32), follow recognised Australian charging practices and codes of practice, including AIRAH guidance and local WHS rules.

Compatibility & System Info

• Use with: any refrigerant charged by weight (e.g., R32, R410A, R134a) — the scale doesn’t contact refrigerant.
• Best paired with: a quality manifold set and hoses for accurate pressure/weight workflow (Mastercool Manifold Gauge Sets).
• Work environments: rooftops, plant rooms, residential installs; keep platform level and dry.

Local Job Notes

Whether you’re commissioning in humid Brisbane or hauling bottles across a windy Sydney roof, the 98201’s big capacity and backlit display help you keep the charge on spec — she’ll be right once it’s charged by weight.
