QUART didoEASY MR

X-Ray Multi-Meter for Service and QA

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 exposure time. Of course, as with all QUART meters – with maximum precision.

- kVp / PPV measurement available in the (optional) QUART didoEASY+ MR version.

- Direct-HVL and kVp / PPV measurement available in the (optional) QUART didoEASY++ MR 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 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.
