YOKOGAWA TM20 THERMO-COLLECTOR

YOKOGAWA TM20 THERMO-COLLECTOR

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.
