Dolphy Evolution

Radiation meter to hotspot search and control

This devices is designed to measure the dose rate, especially for nuclear power plant workers. Its simplicity make him usable for anyone. Its dimensions, its battery lifetime and its drop and immersion resistances make it a simple and robust tool.

Dolphy Training

Gamma radiation simulation system

The set Remote control and Dolphy Training allows to simulate irradiation situations in order to train the Dolphy Evolution users. The ergonomics has been studied to give the Remote control Training a blind one-handed use. For this purpose, there are notches providing access to presets (0.001, 0.025, 1, 2, 99 mSv/h and saturation).
A vibrate mode also helps the trainer know the current value without looking at the Remote control Training screen. By inserting the Dolphy Training into the SAG-A beacon, the trainer can simulate dose rate rises, trigger alarms and observe the trainees’ behavior.
