Environmental Monitoring & Industrial Hygiene Instrumentation Brandt Instruments Distributing Testo

Testo 475 Optical Non-Contact Tachometer
Tachometers, contact, non contact, optical RPM measurement

	Easy non-contact and mechanical rpm measurement The Testo 475 has the ideal combination of optical and mechanical rpm measurement. Testo 475 is a convenient tachometer for measurement of both rpm and frequency oscillation.
	Advantages: Measurements possible in inaccessible places on account of the handy probe design High-Speed measurement feature using a "Fast Finder" function Reflective markings on the measured object are not required Production processes are not interrupted Two-line display gives simultaneous display of rpm and frequency Optional connection of a mechanical rpm sensor
	Convenient and easy measurement of rpm, speed and length in industry Rpm measurement in a reduced d.c. motor Mechanical rpm measurement on a roller e.g printing machines Measured Speed of a conveyor belt in a production company Speed and length measurement on hoisting winches
