QUART didoEASY M
Precision Dosemeter for X-Ray Service and QA
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.
