GRAPHTEC IWATSU Universal Counters SC-7217A / SC-7215A | PT. NIHON DENKEI INDONESIA Jakarta

Up to 3GHz (SC7217A), display up to 12 digits / second

Easy operations with single key strokes for each action. Universal counters feature frequency, cycle, time interval, pulse width, phase, frequency ratio, duty ratio, cumulative count, and peak voltage measurements for easy, versatile measurement. As a basic piece of measurement equipment for development work and technical education, they are also ideal for introduction to production and inspection lines.

• Comparator and statistical operation function make it easy to improve the efficiency of line inspection work.
• It is easy to check the waveform amplitude by measuring the peak voltage of the input signal.
