Microsecond counter (115 V 50/60 Hz)

Product Overview

Application:?.. The microsecond counter is a component of experiments to determine the speed of sound (item no: 8000566) and a required accessory for Kundt s Tube E (item no: 1017339). The microsecond counter is used in conjunction with the microphone box. Product Information:?.. The microsecond counter is a compact counter for measuring time in microseconds. It is especially well suited for measurements made in conjunction with Kundt?s tube and the microphone box. The counting process is start via the Start input and halted via the Stop input. The count is automatically reset back to zero on each start. Both inputs respond to rising edges and have internal pull up resistors. Specifications:?..
