B2-39

DC voltmeter B2-39 is a highly sensitive device that allows to measure DC voltages of both polarities in a wide range.

The device has a built-in functions such as digital filtering and storage, followed by the issuance of the interface, analog output, or the display 100 results.

The ability to self-calibration and the compensate for external destabilizing factors make the device pretty easy to use.
