Reed Instruments Model H Precision Speed Indicator
The instrument has a large, easy-to-read dial, with black figures indicating revolutions per minute and red figures on the inner circle indicating feet per minute readings, without any calculations.
This precision speed indicator is a high precision indicator for the accurate measurement of revolutions per minute or linear speeds in feet per minute. Being of the chronometric type, with a built-in timing element operating over a fixed period of three seconds, this speed indicator is especially suitable for accurate measurements of constant speeds. Accuracy is ±0.5% over a range of 0 to 10,000 rpm and 0 to 3,000 fpm.
The instrument operates in a totally automatic fashion. Once the start button is depressed, the indicator will begin to register revolutions over a fixed period of three seconds. The hands then stop and the reading may be taken from the dial at leisure. The pointer remains in a fixed position until returned to zero by depressing the reset button.
