DOPLHY FROTTIS

Measurement or screening of surface contamination for beta rays. Can be used for Alpha contamination provided the type of contamination is identified. Compact meter designed to simplify smear measurement. Direct display of result in Bq/cm² for 300cm² smear. Extremely lightweight. Steel grid to protect the detector from shocks. Easy to use. Detection characteristics Reference value: Activity referred to a 300cm² smeared surface. Detector: Pancake-type Geiger Müller sensitive to beta from 15 keV and alpha from 4.5 MeV. Unit: Bq/cm² Reference source: 60Cs Sensitive area: 15.9 cm² Sensitivity a and β: 4.5 C/s / Bq/cm² Display range: 0 to 199.99 Bq/cm² Response time: <1 second during a significant variation from 0 to 23 Bq/cm² Integration time: Automatic from 0.5 to 60 seconds. Mechanical and environmental specifications Dimensions: 114 x 72 x 34 mm Weight: 320 g including battery Protection class: IP54 Electrical data Power supply: 9V battery Autonomy: 80 hours for activity < 4 Bq/cm² Application and use Smear measurement, indirect surface contamination control up to 300 cm². Control of equipment and tools at the end of the worksite. Control of cleanliness of installations. Control after decontamination.
