Key takeaways
- Normalise units before comparing — ml/min, % purity, ppb, kg.
- Note peak vs sustained for output and run-time.
- Weight columns by your priorities, not the brochure layout.
Build your own table
Pick six columns: output (ml/min), purity (%), continuous run-time (min), dual user (Y/N), warranty (months), price (currency-normalised).
Fill it from manufacturer spec sheets. Anything missing is itself a signal.
