Start with the workflow, not the device
The most common purchasing mistake is comparing specification sheets before defining how the assessment will fit into a real appointment. Decide first who performs the measurement, how long the appointment slot is, who explains the report to the patient, and where the result is stored.
A device that measures in sixty seconds but requires ten minutes of manual data entry is slower, in practice, than a device that measures in two minutes and prints a finished report.
Questions about the measurement method
Ask whether the analysis is segmental or whole-body, how many frequencies are used, how many electrode contact points exist, and whether the manufacturer documents its measurement approach. These are factual, verifiable attributes — a supplier should be able to point you to official documentation for each one.
Be cautious with any supplier who answers questions about method with outcome claims. Method is documentation; outcomes are clinical territory.
Reporting and interpretation
Request a real sample report, in the language your patients read. Review whether the layout is understandable without training, whether results are trendable across visits, and whether the report can be exported or printed in your normal workflow.
Service, parts and continuity
Equipment value collapses when it is unavailable. Confirm warranty scope in writing, expected response times, whether spare parts are stocked in your region, who performs installation and calibration, and what training is included for new staff.
Documentation and regulatory scope
Ask for the manufacturer's declared intended use and the market authorization status applicable to your country. Authorization in one market does not imply authorization in another, and a distributor cannot extend a manufacturer's declared scope.
