A tachymeter or RPM counter is used to measure the rotation speed. This tachometer works by contact the measurement is taken directly into contact with the device and reads the RPM and the linear speed of the surface. This high precision mechanical tachometer is easy to use and offers a competitive price. At the touch of a button, this handy tower counter measures the rotation speed of moving objects. A micro chip with integrated LSI circuit accurately counts the number of revolutions in a minimum of time. Features: - Measures RPM and linear surface speed. - 18 mm 5-digit LCD digital screen. - Automatic measuring range. - RPM measuring range: 0.5 - 9999.9 / 10000 - 99999 RPM. - Resolution; 0.1 RPM (0.5 to 9999.9 RPM) / 1 RPM (>10000 RPM) - Linear speed measurement range (m/min): 0.07 - 2000 m/min - Resolution: 0 m/min (0.05 to 100 m/min) / 0.1 m/min (>100 m/min). - Length measuring range: 0.05 - 100000 m - Resolution: 0.03 m. - Accuracy: ± (0.05% ± 1 digit). - Memory function: last measured value, maximum value, min value. - Powered by 3 x 1.5 AA batteries (not included). - Dimensions: 220 x 76 x 30 mm - Weight: 200 g.
