Dolphy Frottis
A compact contamination survey meter designed to ensure your safety
This device is designed to measure or detect any beta radiation surface contamination. It is intended for alpha contamination provided that the type of contamination has been previously identified. It is ideal for wipe measurement during 300 cm² indirect surface contamination inspections. The steel grid protects the detector against shocks and makes it suitable for site tools and equipment inspection. The Dolphy Frottis ensures the facility's cleanliness inspection following decontamination.
