DESCRIPTION

SOLID STATE DIGITAL

METER MODULES

Applications

These models offer a variety of functions, sizes,

voltages and customizable options to fit most

applications. Ideal for OEMs, contract manu-

facturers, and panel makers for monitoring

equipment usage, scheduling maintenance,

warranty validation, rental/leasing use and

more. Used extensively in industrial, agricultural,

military & specialty vehicles, as well as applica-

tions such as: vending machines, medical &

office equipment, fuel pumps, and consumer

products.

Features
