The Ono Sokki GE‑1400 is a handheld diesel engine tachometer designed specifically for precise RPM measurement on four-cycle diesel engines. It operates by clamping a dedicated detector to the fuel injection pipe, offering fast, accurate readings and built-in data storage to simplify engine diagnostics..
The GE-1400 is engineered specifically for diesel engine speed measurement, using the CP-044 clamp-on detector to sense pulses generated by fuel injection in four-cycle diesel engines. The periodic signal method ensures precise RPM detection across a wide range of speeds.
Users can fine-tune readings with adjustable trigger levels and selectable gain settings, accommodating different fuel pump designs and signal strengths. The device’s built-in memory allows storage of up to 20 RPM values, enabling convenient data review.
Its output capabilities include analog, monitor, and pulse signals for integration with recorders or analyzers. The lightweight, handheld design, combined with a backlit LCD display and optional tripod mounting, makes it suitable for both stationary testing and mobile diagnostics.
Purpose-Built for Diesel Engines – Optimized for four-cycle diesel engine RPM measurement.
Clamp-On Detector (CP-044) – Detects vibration or pulsation directly from the fuel injection pipe for reliable measurement.
Data Storage – Built-in memory stores up to 20 measurement values, even when powered off.
Multiple Outputs – Includes analog, monitor, and pulse outputs for external recording and analysis.
Clear LCD Display with Backlight – Ensures easy visibility in all lighting conditions.
Adjustable Settings – Rotary knob for trigger-level adjustment and gain selection for various engine types.
Stable Mounting Option – Equipped with a tripod screw hole for steady measurements.
Portable Power Options – Operates on AAA batteries or optional AC adapter for flexibility.
Durable Build – Designed for consistent performance in diverse operating conditions.
