Added kV and Direct-HVL Measurement

 

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+ M version.

- Direct-HVL and kVp / PPV measurement available in the QUART didoEASY++ M 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 M meters automatically compensate for Mo/Mo beam quality. Corrections factors are provided for further radiation qualities.
