Model: SE-2500A

SE-2500A is a non-contact handheld tachometer designed for gasoline engine measurement. Detection, measurement, and display parts are all in one unit and batteries are built in the unit. Moving the detector (head of the SE-2500A) close to an ignition coil can measure rotation speed at the unit of 1 r/min or 0.01 r/s. Up to 20 measurement data can be stored in the internal memory that is convenient for later checking.

Both analog (able to switch over to monitor output) and pulse outputs are provided as standard. Analog output signal can be used for the data recording by recording device. Monitor output is used for checking sensor waveform or input signal of FFT Analyzer. Pulse output signal is used for tracking analysis signal for FFT Analyzer.

* IP-2800 External sensor (discontinued) is not provided as standard.

Specifications Summary

Calculation method

Cycle calculation method

Measurement time

Within 1s + the time required for one cycle of input signal

Measurement unit

r/min, r/s

Measurement ranges

2-cycle	4-cycle	Number of rotations (r/min)
-	1 cylinder	120 to 20000 r/min
1cylinder	2 cylinders	120 to 20000 r/min
-	3 cylinders	120 to 20000 r/min
2 cylinders	4 cylinders	120 to 20000 r/min
-	5 cylinders	120 to 20000 r/min
3 cylinders	6 cylinders	120 to 15000 r/min
4 cylinders	8 cylinders	120 to 12000 r/min
-	10 cylinders	120 to 10000r/min
-	12 cylinders	120 to 8000r/min

(r/s is the numerical value obtained when the r/min measurement value is divided by 60)
