Gasoline Engine Tachometer
SE-2500
Both analogue (which can be switched over to monitor also) and pulse output function are provided as standard. Analogue output signal can be used for the recording the signal from data recorder and so on. Monitoring output signal can be used for checking the sensors detection waveform or as the input signal by FFT analyzer. Pulse output signal can be used as external clock signal for tracking analysis by FFT analyzer.
IP-2800 External Sensor (Accessory)
Featute
Built-in memory function 20 data (MAX) can be saved to memory.
Three outputsanalog, monitor and pulseprovided as standard
Large LCD with backlight
Capable of performing measurement at a distance of 1 m when the external sensor (IP-2800) is used.*
Can be mounted on a tripod
Measurement can be performed in 1 r/min or 0.01 r/s units.
*Measurement is impossible depending on the type of the engine.
