Digital Tachometer Non-Contact RPM Meter with 0.05% Accuracy and 99,999 RPM Range

This digital tachometer provides a reliable, non-contact method for measuring rotational speed on a wide variety of machinery. Whether you are maintaining automotive engines, checking conveyor belt rollers, or testing industrial fans, this instrument delivers accurate readings from 2.5 RPM up to 99,999 RPM. Its automatic range switching and built-in memory for last, maximum, and minimum values make it a practical tool for diagnostics and routine checks. The dark grey ABS plastic body is lightweight and compact, fitting comfortably in the hand for extended use.

Features and Construction

The tachometer is built around a precise 6MHz crystal oscillator time base, ensuring consistent and repeatable measurements. It offers a clear 5-digit LCD display with 18mm (0.7") digits, making readings easy to see even in varied lighting conditions.

Material and Build

Made from dark grey ABS plastic, the housing is both lightweight (79g) and impact-resistant. The compact dimensions of 130 x 70 x 29mm make it easy to store in a tool box or carry on site.

Size and Practical Fit

The device's 50-500mm measuring distance allows you to stand safely away from moving parts while still obtaining accurate readings. Its automatic test range switching eliminates manual guesswork, and the 0.8-second sampling time (for speeds over 60 RPM) provides quick feedback.

Uses and Placement

This tachometer is suitable for a range of professional and hobbyist applications where rotational speed needs to be monitored or recorded.

Event or Professional Use

In industrial settings, use it to measure the RPM of motors, pumps, compressors, and conveyor systems. The last, maximum, and minimum value recall helps identify performance variations over time.

Everyday Home Use

For home workshops, it can check the speed of bench grinders, lathes, fans, or bicycle wheels. The non-contact method means no mechanical load is applied to the rotating part.

Benefits and Buying Value

This tachometer offers reliable performance without the need for physical contact, reducing wear on both the instrument and the target. Its automatic features simplify operation while maintaining high accuracy.

Reuse and Low Maintenance

With no moving parts to wear out, the device requires minimal maintenance. The battery compartment uses a standard 9V battery (not included), which is easy to replace when needed.

Why Choose This Product

Its wide 2.5-99,999 RPM range and 0.05% accuracy provide confidence in measurements across many applications. The included reflective tape marks and comprehensive user manual get you started right away.
