PZ158A DC digital voltmeterDetailed product description：

Product Description
The PZ158A series DC digital voltmeter has a 6 1/2 bit display and can measure DC voltages ranging from 0.1 µ V to 1000V. Due to the use of microprocessors and pulse width modulation analog-to-digital conversion technology, automatic zero calibration, digital analog filtering and other technologies, this meter is endowed with extremely stable zero position and good linearity and anti-interference ability. It also has an RS232C interface, which can be easily connected to computer systems to form a data acquisition system. Adopting an eight bit VFD or LED display, PZ158A/1 is a single range (0.2V) VFD display with clear readings and soft light colors, suitable for use in various fields such as scientific research, industry, and national defense.
