La description

The TM20 offers excellent data management functions: Collect up to 5000 data items with time-stamp, tag name and inspector name. Save 2 weeks continuous data logging with 1 minute interval (up to 20000 data items, measuring interval is 1sec. to 24 hours.). Information on when, by whom and what is measured is saved along with the data.
