EHDIS LH900RF Digital No Contact Tachometer with Reflective Tape

Description

Product Overview

The EHDIS LH900RF is a handheld, gun‑type digital tachometer designed for non‑contact speed measurement. It operates with a single 9V battery and features a robust plastic housing that resists drops and industrial wear. The device measures RPM from 2.5 up to 99,999 using a reflective tape that you apply to the rotating part. A 2‑inch LCD screen shows the current reading, and automatically stores the last, minimum and maximum values for quick reference. Dimensions are compact at 5.91 x 5.12 x 0.79 inches, weighing just 4.66 ounces, making it easy to carry on the shop floor.

Usage

Designed for industrial and scientific environments, the LH900RF excels in measuring the speed of circular saws, lathes, conveyors, fans and other rotating machinery. Its 2‑20 inch (50‑500 mm) measurement range allows technicians to take readings without stopping equipment, reducing downtime. The included silver‑gray reflective tape can be cut to size and affixed to any surface, ensuring a strong return signal even on matte or painted parts. Ideal for maintenance crews, quality control inspectors and hobbyists who need fast, accurate RPM data.
