Digital Tachometer – Photoelectric RPM Meter

The Digital Tachometer is a professional photoelectric measuring device designed for fast and accurate non-contact RPM measurement of rotating components and machinery.

Using photoelectric measurement technology and an integrated quartz-controlled LSI microchip circuit, the device delivers rapid and highly accurate readings over a wide measurement range.

The large LCD display provides clear visibility of measured values and function indicators while reducing reading errors and power consumption. Memory functions automatically store the last recorded value together with minimum and maximum measurements for easier monitoring and comparison.

The lightweight and ergonomically designed ABS housing ensures comfortable operation while providing durability suitable for daily workshop and industrial use.

The device is delivered in a protective plastic case with reflective test strips and operating instructions.
