DT 65 is a digital handheld tachometer, or rotation meter, that can take both contact and non-contact measurements of rotation speed and linear speed. This handheld tachometer features an integrated laser and includes a mechanical attachment with contact probes, making it the ideal measuring instrument for machines, motors, conveyor belts and other moving parts. Non-contact measurements are taken with the help of laser-reflective tape that is fixed on the moving part. Contact measurements are taken using the included mechanical attachment and contact probes.
