QUART didoSVM

Ortsdosismessgerät für Beta-, Gamma- und Röntgenstrahlung 20 keV - 2 MeV

Das QUART didoSVM Ortsdosimeter misst Air Kerma, Umgebungsäquivalentdosis (H*10) und Richtungsäquivalentdosis (H'0.07) für Streustrahlung, Sekundärstrahlung und Strahlung hinter Strahlenschutzabschirmungen an Röntgen-, Gamma- und Beta-Strahlenquellen.

The detector of the QUART didoSVM is compact and light-weight, thus making handling the meter a breeze. As its technical concept is based on solid state technology, the meter provides all the advantages connected with this approach: fast response time to radiation, reproducible measurement results and accurate detection of signals against background noise. Radiation is detected from leakage, scatter beams and pinholes.

Usability

Although base unit and detector are separated, both may be combined magnetically to carry and use the meter with one hand.

The detector can be mounted on a tripod or a telescopic extension to allow measurements in heights up to approx. 3.5 meters above the ground.

The didoSVM is equipped with a backlit display to assure swift readings even in darkened environments. To provide the ability to track dose rate characteristics, the dose rate is refreshed continuously on the meter display while the measurement is running.
