The IP65 shock-proof , mobile-size aluminium case weights 250 grams. It can be easily worn by using the built-in clip. Beside key pad and the special cap for gas entry into the measurement chamber, a three line LC display completes the functional designed front side. Power supply by a built-in NIMH rechargeable battery ensures a full time use of more than 300 h. The available booster-version enables a stand-alone time up to 1.200 hours. Alarm situations (user-defined) will be signalled by flashlight sound.

The DOSEman records and displays the time distribution of dose and concentration. IrDA infra-red technology provides a comfortable administator desk for setting measurement parameter in dependence on the local ambient conditions. Communications to PC (for instance at the access control desk) are possible in distance up to 1 meter within a time of less than 1 second.
