The 07039.00 is designed for measuring small DC currents. The instrument is quite suitable for experiments in which the zero method is used, for example at Wheatstone bridge.
The 07038.00 is designed for measuring DC currents and is suitable for exercises in which pupils use galvanic couples, batteries and low voltage sources. We suggest one instrument for work of two ...
The 07035.00 is designed for measuring AC/DC voltages. With our ammeter 07036.00 (link at 07036.00) it makes a voltmeter set, suitable for basic and advanced electro-technical and electronics ...
