The SE-1200 is a new-designed appearance of our long-selling digital engine tachometer. Indigo blue in color, it is designed to fit snugly into the palm of your hand. A memory function (10 data) has been added to the original specifications of previous model.

Featute

A large-size LCD device has been incorporated into the compact, lightweight body.
Easy and safety operation by non-contact measurement.
Measurement can be performed in 1 r/min resolution covering a wide measurement range.
The cylinder/cycle settings enable use with various gasoline engines.
Equipped with a convenient memory function for checking of the measurement results (up to 10 data can be stored in memory.)
Over-range display function—if the measured value exceeds the measurement range, the maximum value for that range is displayed together with an “ERROR” mark.
After measurement has been completed, the latest measured value is displayed for approximately 30 seconds.

Gasoline Engine Tachometer

SE-2500A

SE-2500

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.

VP-201/1210
External detector (option)

Featute

Easy and safe measurement by non-contact measurement method

Accurate rotation speed measurement by the unit of 1 r/min or 0.01 r/s

Easy to identify the displayed value with large LCD with backlight even when the surrounding is dark

Up to 20 data can be stored by memory function

Analog output	0 to 1 V/0 to F.S (F.S. : can be set optionally), 10-bit D/A conversion
Pulse output	Hi : +4.5V or more, Lo : +0.5V or less

Rotation speed of 4-cilinder diesel engine can be measured with the VP-201/1210 (optional detector) *

* It may not be measured depending on an engine.

Analog and Pulse outputs are provided as standard
