X-ray patient dosimeter dido/time RF

Product Overview
The QUART dido/time meters are designed for simple and straight-forward dose/dose reference measurements as required in x-ray routine QA/QC. Routine tests are usually carried out in regular intervals to assure the adequate performance of x-ray equipment. The QUART dido/time meters are ideal tools for that application.

Usage
The meters are ready for use immediately after activation. No presetting procedures are required. Simply position the detector and expose to acquire the routine check parameters. The QUART dido/time RF features a detector embedded in a 25.0 mm Al patient equivalent filter. Such a set-up had been introduced in German QA regulations to simulate x-ray imaging reality in quality control processes. In x-ray quality control the meters are used together with an image quality control phantom.
