didoEASY R / didoEASY+ R / didoEASY++ R
Since the meters do not require any pre-setting procedure, measurement results are acquired very quickly:
1. Position the detector and switch on the didoEASY meter...
2. Set the x-ray equipment to the desired parameters...
3. Expose... - and simply read all measurement information from the meter‘s display. The QUART didoEASY meters automatically compensate all major medical x-ray beam qualities. No further corrections or compensations are required.
Traditionally, the detector of the QUART didoEASY meter series also measures the integrated dose-width product (DWP) at dental panoramic equipment.* A feature that provides real added value for QUART users.
