dBAlert! activates only when the noise exceeds a pre-set level, warning exposed workers that noise levels have become dangerous and to put on their ear-defenders. Perhaps more importantly for the employee, this means that they will also know when they can legally take them off!

Being of rugged construction, dBAlert is suitable for most industrial situations. It comes complete with a pocket clip and the membrane keypad means that integrity and simplicity of use are maintained.

dBAlert! also includes a vibrating alert , which gives the wearer the added warning of a mobile phone style vibrating alert to bring attention to the fact that dangerous noise levels have been exceeded.
