Dental RPM Pro is a high speed acoustic rpm meter fully capableof measuring high speed air-driven handpiece free running speeds upto 550,000 rpm. Its capability in electric handpiece rpm has notbeen fully explored. At this time, this app is not recommended forelectric handpieces. Dental RPM Pro makes very accuratemeasurements of high speed handpiece rotational speed with itsproprietary frequency analysis algorithm that distinguishes thesound corresponding to the shaft rotation from other noisesgenerated during handpiece operation. Even in a situation wheremultiple handpieces are operating simultaneously, it correctlycaptures the nearest handpiece’s rpm. The app also reports the peaknoise level (A-weighted) of handpiece at the time of measurement.This app is compatible with all Android devices with Android OSversion 2.2 or higher. A patent is pending on major features of theapp including its functionality and frequency analysisalgorithm.
Features
- Steady-state speed in revolutions per minute (rpm) between25,000 and 550,000 with an accuracy of ±2584 rpm within 10 cm to 3m (4 inches to 10 ft) distance from the handpiece.
- A-weighted noise level with an accuracy of ± 3 dB. Recommendeddistance for dental handpiece noise measurement is 45 cm (18inches) from the head.
- Hold button to freeze the reading (hit again to resume).
The app will display 0 rpm upon launching. Hit "Set dB" buttonto start (while handpiece is not operating).
