3 1/2 5V RED LCD Digital Volt Panel Meter DC 0~±20V NEW

Brief Introduction:

This panel meter employs large-scaled IC and stable bandgap reference. Its peripheral circuit integrates imported precise components, which makes it more stable than other competitive panel meters. A standard size makes installation convenient. It can widely be used in applications like scientific research tools, audio-visual education and instrumentations.
