The product arrives in a small white box, and it contains the product in plastic packaging (factory calibrated from a Cesium source). A set of batteries inserted in the back, in a plastic bag and the user manual and certificate of conformity and test. The product is used very simply, either direct measurement or background, you can set an alarm from a threshold (default is 0.3 micro-sieverts per hour where the natural rate radioactivity is about 0.1 micro Sv).
It fits in your hand, it is small and handy. The Geiger-Muller tube is located on the left side when you hold the device in front view. Couvecle The back has an orientation direction (a stretch, a curved end) indicating the direction of polarity: no mistake when you put the batteries so.
I put some pictures with my comments: contents of the box, battery installation, and operation.
