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.
