EchoTach, the new optical tachometers from RheinTacho are now available from SI Instruments .
These hand-held, non contact optical tachometers are perfect for checking rotational speeds quickly and accurately.
The pocket-sized optical tachometers are lightweight, and they have a measuring range of 1 through to a whopping 60,000 rpm.
A red LED light beam is expelled from the tachometers and reflected by a reflection mark that is fixed on the equipment to be measured. The result can be read from up to 450mm distance and at a very wide angle.
The optical tachometers feature a very bright LED and matching optical system to ensure that they are resistant to unrelated light rays that may fall into the same path as the light beam that they expel.
The large LCD makes the measurement easy to read, and the last measurement is stored for 30 seconds, giving plenty of time to note the rpm results.
The tachometers are very efficient, as they automatically shut down after they have taken a measurement and waited the 30 seconds in order to conserve battery life.
The EchoTech optical tachometers are manufactured in Germany and they are extremely durable. They come with a two year warranty, and weigh a mere 147g including batteries.
