MT-900 supersedes the conventional MT-700 model. We have provided two new calibration curves under the labels “Broad-leaf” and “Conifer”, and by using these curves, it is possible to cover a wide moisture range – 6-80% (Broad-leaf) and 7-80% (Conifer). It is also possible to call up the calibration curves of the original 16 tree species. Furthermore, we have provided a printer output terminal so that data can be printed out by connecting to an optional printer.
