15 Reshipment and Disposal
15.1 Reshipment
All devices returned to the manufacturer have to be free of any residual of measuring media and
other hazardous substances. Measuring residuals at housing or sensor may be a risk for
persons or environment
Use an adequate transport package for reshipment, especially for fully functional devices.
Please make sure that the device is protected in the package by enough packing materials.
15.2 Disposal instructions
Batteries must not be disposed in the regular domestic waste but at the designated collecting
points.
The device must not be disposed in the unsorted municipal waste! Send the device directly to us
(sufficiently stamped), if it should be disposed. We will dispose the device appropriate and
environmentally sound.
