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 most beam qualities. No further corrections or compensations are required.
Like the QUART dido2000 series meters, the detector of the QUART didoEASY meter series also measures the integrated dose-length product (DLP/DWP) at dental panoramic equipment.* A feature that provides real added value for QUART users.
