Precision Speed IndicatorAll units supplied with case, 2 tips, and 1 surface wheel for measuring RPM and surface speeds in FPM

The Precision Speed Indicator is a high precision indicator for the accurate measure-ment of revolutions per minute or linear speeds in feet per minute. Being of the chrono-metric type, with a built in timing element operating over a fixed period of three sec-onds, this speed indicator is especially suitable for accurate measure-ments of constant speeds. Accuracy ±0.5% indicated.

The instrument operates in a totally automatic fashion. Once thestart button is depressed, the indicator will begin to register revolu-tions over a fixed period of three seconds. The hands then stop and thereading may be taken from the dial at leisure.The pointer remains in a fixed position untilreturned to zero by depressing the resetbutton.

The instrument has a large, easy to readdial, with black figures indicating revolu-tions per minute and red figures on the inner circle indicatingfeet per minute readings, without any calculations.

Types D1/D2 Vibrating ReedTachometersCompact Size

Smaller in size than the H Type Tachometers shownabove, these tachometers have smaller and fewer reeds.Being more compact, they are ideal for tool case or pock-et use. Moderately priced, they are the answer to manyspeed measuring problems. These instruments are verypopular in the textile industry for measuring speeds ofsewing machines. Other typical applications are out-board motors, electric shavers, centrifuges, etc.

Type H Vibrating Reed TachometersAccurate—Rugged—Dependable

Because these tachometers measure speeds by con-tact, this type of tachometer is the solution to manyspeed measuring problems, especially checking speedsof totally enclosed rotating equipment. These tachome-ters operate on the well known and time tested princi-ple of resonance. The instrument is simply held againstmotor, turbine, pump, compressor, or other rotatingequipment and the speed is shown by the vibration of asteel reed which is tuned to a certain standard speed.

Ruggedly constructed, permanent accuracy, simpleto use. The instrument imposes no load and cannot bedamaged by overspeeding. Accuracy is 0.5% of ratedspeed.
