PZ158P type panel type DC digital voltmeterDetailed product description：

The PZ158P panel type DC digital voltmeter and ammeter are a series of extensions based on the 5/2 voltmeter. They adopt the ∑ - Δ A/D conversion principle and have the characteristics of high measurement accuracy, digital filtering, fast averaging, and automatic calibration. The instrument display adopts a seven digit LED display, which can easily achieve digital measurement of various electric and non electric quantities. It is an ideal matching instrument for various measuring instruments and consoles. Users can also choose to have an RS232 interface.
