เครื่องวัดความเร็วรอบ Tachometer Gasoline Engine

DT-2237A จุดเด่น

Wide Compatibility: Suitable for both 4-cycle and 2-cycle engines, regardless of the number of cylinders. It can measure engines with 2, 3, 4, 5, 6, 8, 10, and 12 cylinders.

High Accuracy and Resolution: Provides precise RPM readings with an accuracy of ±(0.05% + 1 digit). The resolution is 0.1 RPM for readings below 1,000 RPM and 1 RPM for readings 1,000 RPM and above.

User-Friendly Display: Features a 5-digit LCD with 10 mm (0.4 inch) high digits for clear and easy-to-read measurements.

Memory Function: Capable of storing the last value, maximum value, and minimum value, allowing users to track and compare measurements effectively.

Durable and Portable Design: Constructed with a durable ABS plastic housing, and includes a carrying case for easy transport and protection.
