NTC-05.56 “Teaching digital device”

Br0.00

The laboratory stand “Teaching digital device” is designed to be used as a teaching facility for practical laboratory tests in Universities and specialized secondary schools to measure voltage, current, power in alternating and direct current circuits, phase-shift angle between voltage and current in alternating current circuits.

A distinctive feature of this training system is the ability to record instantaneous values of each measured value, with an interval of 0.5 seconds.

The recorded values are read using a personal computer via the USB interface. The package also includes software and drivers for Windows operating systems.
