Function of panel meter

What is a Panel Meter? A panel meter is an instrument that displays an input signal in either a digital or analog form. Many panel meters also include alarm options as well as the ability to connect and transfer data to a computer. OMEGA's iSeries panel meters are available with an ethernet option which allows the panel meter reading to be accessed across a local area network (LAN) or even through the internet.
