The CT-6520B universal engine tachometer enables direct reading of signal from 0.5 to 199.5 P/R in r/min-unit. The analog output helps to grasp an overall trend and see fluctuation by connecting to a recording device such as a pen recorder or other display devices.

Since the circuit is originally designed to change signal into the amount of analogs after multiplying the input signal and making it a fixed pulse train, the CT-6520B can perform high precision measurement with high tolerance for noise.

Features

Even low pulse signals can be read directly in r/min-unit.
Easy to read by large LED
Three types of output (digital, analog and pulse) as standard
2 ways of power operation ; AC (ranging 100 to 240VAC) and 12VDC (ranging 11 to 15VDC)
