The doublesided chest piece can be switched from diaphragm to bell mode by twisting the tube. The exchangeable diaphragm is reinforced with fibre-glass and is therefore especially sensitive.

The available selection of eight different colours almost completely eliminates the possibility of users confusing their instruments for someone else’s. __User’s manual Learn more about Kirchner COLORSCOP® Duo
