Contact and non-contact RPM measurement

The CEM AT-8 is a digital tachometer designed for electricians and technicians who need to measure rotational speed on motors, fans or shafts. It operates in both contact and non-contact modes, using a built-in laser pointer for distance readings. The unit stores up to 40 readings in memory for later review. A five-digit LCD shows results with a resolution of 0.1 RPM up to 9999.9 RPM.

Suits maintenance and inspection tasks

This instrument suits users who require a single tool for contact measurements up to 20,000 RPM and non-contact measurements up to 99,999 RPM. It is not suited for applications that demand non-contact readings beyond 99,999 RPM or for users who need an English manual included in the box. The package does not contain batteries, which must be sourced separately.

Maximum non-contact range 99,999 RPM

The decisive specification is the non-contact measurement ceiling of 99,999 RPM, which determines whether the meter covers the target equipment. Contact mode reaches 20,000 RPM, while total count capacity reaches 99,999. Accuracy is rated at ±(0.05% + 1 digit) with a sampling time of 0.5 seconds above 120 RPM.
