2003 09 ==> Tachometer

For sale is a military surplus Strobetac universal tachometer/RPM meter by Jones Motrola Corp from Stamford CT. A very nice unit measuring 0-14,000 RPM. I tested it with my drill that is known to have 25oo RPM, and alas, the unit showed exactly 2500 RPM. It has all kinds of attachments for all kinds of rotors etc. All attachments are in place. Please check out the calibration sticker for calibration info.
