An optical tachometer for measuring speeds of rotating objects in RPM. It also measures surface speeds in metres per minute or feet per minute. High accuracy is achieved by combining CPU, photoelectrical and laser techniques. The ergonomic design makes the instrument comfortable to use.

Optical Measurements:
_x000D_ RPM and totalise counter, being non contact via supplied reflective tape
_x000D_ Impact resistant ABS case
_x000D_ Laser spot for easy identification of target
_x000D_ Optical detection distance 50mm to 500mm
_x000D_ 50mm LCD display with function indicators
_x000D_ Recall of last measured value
_x000D_ Min/max memory updated automatically
_x000D_ Low battery indicator
_x000D_ Sampling rate of 0.8 seconds (over 60 RPM)
_x000D_ Supplied with foam padded carry case, 700mm reflective tape & batteries
