didoEASY MR / didoEASY+ MR / didoEASY++ MR
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 R detector automatically compensates all major medical x-ray beam qualities. No further corrections or compensations are required.
The M detector for mammography automatically compensates for Mo/Mo beam quality. Corrections factors are provided for further radiation qualities.
Like the QUART dido2000 series meters, 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.
