Sticht AO-98806-07 6239 Vibrating Reed Tachometer; 1000 to 5500 rpm

Accurate - rugged - dependable because these tachometers measure speeds by contact, this Type of Tachometer is the solution to many speed measuring problems, especially checking speeds of totally enclosed rotating equipment. These tachometers operate on the well known and time tested principle of resonance. The instrument is simply held against motor, turbine, pump, compressor, or other rotating equipment and the speed is shown by the vibration of a steel REED which is tuned to a certain standard speed. Ruggedly constructed, permanent accuracy, simple to use. The instrument imposes no load and cannot be damaged by over speeding. Accuracy is 0.5 percent of rated speed. Compact size smaller in size than the standard tachometers, these tachometers have smaller and fewer reeds. Being more compact, they are ideal for tool case or pocket use. Moderately priced, they are the answer to many speed measuring problems. These instruments are very popular in the textile industry for measuring speeds of sewing machines. Other typical applications are outboard motors, electric shavers, centrifuges, etc.
