Our Products
We are leaders in the market for providing best range of Digital Tachometer, Engine Tachometer, Industrial Analogue Tachometer and Laser Tachometer
The Contact Type Digital Tachometer is a versatile and reliable instrument designed to measure the rotational speed (RPM) of shafts, motors, gears, and other rotating equipment with high precision. It operates on a contact principle, where a sensing wheel or probe is placed directly on the rotating surface, ensuring accurate measurement even under varying load conditions.
The device features a large 5-digit LCD display, which clearly shows RPM readings along with function annunciations. Some models are equipped with an 18 mm high-visibility display, making it suitable for bright or dimly lit environments. Its measurement range of 0.5 to 19, 999 RPM allows it to cover low-speed precision applications as well as high-speed industrial motors.
With dual-resolution capability—0.1 RPM for low-speed measurements and 1 RPM for high-speed operations—this tachometer delivers both accuracy and detail. The device also offers rapid sampling (0.8–1 second) to quickly capture rotational speed changes. The ±(0.05% + 1 digit) accuracy ensures that readings are reliable for quality control, maintenance, and testing purposes.
Powered by 3 AA batteries, the tachometer is lightweight and portable, making it convenient for use in workshops, production floors, laboratories, and field operations. The robust casing and compact dimensions (170 × 70 × 35 mm) provide durability and ease of handling.
Additional features may include data hold, maximum/minimum RPM memory, and automatic shut-off, depending on the model, further enhancing functionality for industrial and laboratory applications.

This is an analog tachometer which can measure RPM of a rotating shaft or peripheral speed without requiring any special stopwatch. Easy to use with excellent accuracy.
As soon as a suitable contact tip attached to the meter is pressed lightly to the rotating shaft center, spindle is turned. When the button on the top is pressed and released, the spring is charged, the clock operates, and the pointers revolve, automatically stopping at certain scale points to show RPM of the measured machine.
Concave rubber contact tip, 1 Convex rubber contact tip, 1 Wheel(pulley) for peripheral speed measuring
