Description
|
This hand-held instrument measures up to 100,000 RPM using infrared measurement. A combination digital/analog bargraph LCD displays the measurement clearly and accurately. Other features include auto or manual range selection, smoothing, min/max recording and hold functions. Count, alarm and print functions are also provided. An accessory kit of three mechanical adapters allows for direct connection and measurement to rotating shafts and other devices. Hi and Lo alarm levels are programmable as well as display multiplier coefficient "K" scale factor). The Model CA27 is supplied in a carrying case with 15 reflector strips, 9V Alkaline battery and a user manual.
