Note: This product has been replaced by PZ158.

The PZ158 series DC digital voltmeter has a 5 half position display and can measure DC voltages ranging from 0.1 µ V to 1000V. Due to the use of a microprocessor and pulse width modulation analog-to-digital conversion technology, the meter can automatically zero and perform digital analog filtering, giving it extremely stable zero position and good linearity and anti-interference ability. The meter also has an RS232C interface, which can be easily connected to a computer system to form a data acquisition system. Adopting a seven digit VFD or LED display, the reading is clear and the light color is soft, suitable for use in various fields such as scientific research, industry, and national defense.
