FEATURES * Compact and pocket tachometer. * The best Tachometer in the world. 2 in 1, one instrument combine Photo tachometer and Contact Tachometer. * Photo tachometer uses Laser light detecting source, long measuring range up to 1.5 meters, it is useful in the RPM measurement application where the machine would be a risk to the operator or close access is difficult or not possible. * Wide measuring range from 0.5 to 100,000 RPM, 0.1 RPM resolution for the measured value < 1000 RPM. * Microprocessor based circuit, crystal time base, high precision with 0.1% accuracy. * High visible LCD display gives RPM reading exactly with no guessing or errors & saves battery energy. * Memory with recall function, the last value, max., value, min. value will be stored into the memory automatically. * The use of durable, long lasting components, including a strong, light weight ABS plastic housing, assures almost maintenance free performance for many years. * RS232 PC serial interface. * The tachometer have patent patented, refer page 10. 1 2. SPECIFICATIONS Measurement Photo Tachometer : & Range 5 to 99,999 RPM. Contact Tachometer : 0.5 to 19,999 RPM. Surface Speed : m/min. - 0.05 to 1,999.9 m/min. ft/min. - 0.2 to 6,560 ft/min. in/min. - 2.0 to 78,740 in/min. Resolution RPM 0.1 RPM ( < 1,000 RPM ). 1 RPM ( 1,000 RPM ). ≧ m/min. 0.01 m/min. ( < 100 m/min. ). 0.1 m/min. ( 100 m/min. ). ≧ ft/min. 0.1 ft/min. ( < 1,000 ft/min. ). 1 ft/min. ( 1,000 ft/min. ). ≧ in/min. 0.1 in/min. ( < 1,000 in/min. ). 1 in/min. ( 1,000 in/min. ). ≧ Display LCD, size 32 mm x 28 mm. 5 digits with display unit. Accuracy ± ( 0.1% + 1 digit ). @ reading Photo 5 to 150 cm typically. Tachometer * Spec. of detecting distance are that detecting under the size of reflecting tape is distance 10 mm square & the measuring RPM value is 1,800 RPM. The max. & min. detecting distance may change under different environment, different reflecting tape or the measuring RPM beyond 1800 RPM. 2
