Skip If You…
Two deal-breakers make this the wrong choice:
- If you need a low-cost portable scale or basic charging tool under $1,000, consider Elitech LMC-300 at $159.99 instead. The Elitech LMC-300 is a high-precision refrigerant charging scale useful for occasional R-134a work. The scale is far cheaper and better suited for occasional DIY jobs than the 34788NI’s full-service automation.
- If you only need a compact handheld recovery machine for occasional jobs, consider Robinair RG3 at $569.99 instead. The RG3 is portable, weighs about 18 lb, and recovers both liquid and vapor for small systems. The RG3 is better for infrequent or mobile work where the full automation and data logging of the 34788NI are unnecessary.
Value Calculation
At $4,650, the Robinair industrial-grade R-134A refrigerant recovery, recycling and recharging machine is priced like a multi-year shop investment and replaces recurring dealer service costs. If a single dealer refrigerant service costs about $300, the 34788NI breaks even after roughly 15 avoided dealer calls, plus it reduces in-shop labor costs per job.
