The QUART didoEASY meters are designed for users who emphasise high precision in dosimetric applications but do not require the performance of a full-range dosemeter package.

QUART didoEASY meters can be used to measure parameters which are essential for service and quality assurance operations at x-ray equipment such as dose, dose rate and time. Of course, as with all QUART meters – with maximum precision.

- kVp and PPV measurement available in the QUART didoEASY+ R version.

- Direct-HVL and kVp / PPV measurement available in the QUART didoEASY++ R version.

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.
