* 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.

* Patent patented.
