CT-6700 Digital Engine Tachometer

Now includes NABL Calibration Certificate.

The CT-6700 is a compact, high-performance digital tachometer designed to accurately measure the rotational speed of gasoline and diesel engines, EV/HEV motors, and general rotating machinery. It supports a broad range of sensor compatibility—including ECU crank signal input—and delivers ultra-fast analog and pulse outputs for seamless speed tracking..

  • Specification

The CT-6700 is tailored for precision RPM measurement across various engine types, including hybrid and electric vehicles. Its high-speed analog and pulse outputs make it responsive enough to capture rapid rotational changes, critical for engine diagnostics and performance tuning.

With compatibility across a wide array of detectors—and the ability to interpret ECU crank signals—it excels in scenarios where traditional sensor attachments are challenging. “Trigger Assist” simplifies setup by automating noise filtering, while CAN output offers direct integration with modern data logging systems.

Additional features such as comparator-based run and over-speed detection, and deceleration estimation for clean engine-stopping readings, make the CT-6700 both reliable and versatile. Its small footprint and optional mounting accessories enable seamless use in both workshop and vehicle environments.

  • Ultra-Fast Response – Analog output follows acceleration/deceleration within one signal cycle plus 8 microseconds, enabling precise capture of transient engine RPM changes.

  • Comprehensive Sensor Compatibility – Supports up to ten sensor types, such as ignition-pulse, engine rotation, magneto-electric detectors, and ECU crank signals for extended measurement capabilities.

  • Automatic Trigger-Level Adjustment – Built-in “Trigger Assist” automatically sets optimal detection thresholds to minimize noise and streamline setup.

  • ECU Crank Signal Recognition – Learns and interprets complex, unevenly spaced ECU crank pulses for accurate speed measurement even without physical sensors.

  • Optional High-Speed CAN Output – Enables real-time digital RPM data via CAN communication (up to 1 kHz), ideal for logging systems.

  • Built-In Comparator Functions – Offers threshold-based engine-start/run detection and over-speed alerts, enhancing monitoring and control capabilities.

  • Deceleration Estimation – On sudden engine shutdowns, the analog output retains estimated RPM values based on last known signal intervals, improving reliability during stops.

  • Compact Design with Panel-Mount Option – Durable and portable (approx. 170 × 49 × 120 mm), with accessories available for integration into instrument panels.

  • Industrial Compliance – Meets CE marking and RoHS safety and environmental standards for professional use.
