ABSTRACT:
A warning and measuring device for personal protection with a rod-shaped casing shape. The shape of the casing allows the device to be suitable 1. for measuring if held in the hand or mounted on a tripod, 2. for warning when carried on the body and 3. for leak detection in hollow conductors. This is made possible through a compact construction and a movable absorber which in an absorber package within a cap can be fitted to the casing while the cap is detachable and can be used as handle on the other end. The device can be economically manufactured and with regard to quality can be considered a high-quality measuring instrument.
