Digital Counters & Frequency Meters
NLS panel mount digital counters, frequency meters, and interval timers are available
in four case sizes and feature a wide range of functions. These versatile, rugged, and low
cost meters find many applications. Features in various meters include highly accurate
crystal time base circuitry, counts of up to one million per second, frequencies to 60
MHz, battery back-up and a presettable decimal point. Multiplexed BCD outputs are also
available for some meters.
