OML 343AC

3 ½  digit AC VOLTMETER - AMMETER

Type OML 343AC is an inexpensive 3 ½ digit panel programmable AC voltmeter - ammeter designed for simple applications with depth of the box of only 30 mm.
The instrument is based on a single-chip microcontroller with a true RMS converter, which ensure good accuracy, stability and easy operation of the instrument.
