The TM20 can accept inputs from a sensor that outputs voltage signals ranging ±100 mV or ±1 V. A U-shaped Miniature connector is required.

Memory Key

Each press of this key saves the measured data, along with 3 other monitoring items: the name of the object being measured, operator’s name, and date and time of measurement.

Selection of registered tag name
