Photo/Contact Tachometer, Motor Tachometer Induction Contact Dual Purpose Linear
Features:
1. Adopt microprocessor (mcu) chip, photoelectric technology, anti Interference technology, semiconductor laser and other advanced technologies to realize the [Non-contact measurement] and [Contact measurement].
2. Wide measuring range and high resolution.
3. Large-screen LCD display, clear reading, no parallax.
4. Automatically store the maximum value UP, minimum value Dn and the last measurement
Last, store about 500 measurement values at the same time, convenient for users to count
and analyze the measurement data (The measurement data is automatically refreshed when you press [Measurement key]).
5. When the battery voltage is too low, the meter displays the prompt symbol.
6. Contact measurement and non-contact measurement, one meter for two purposes.
7. Streamlined ergonomic shape design, make the meter body fit user' palm perfectly to insure more convenient and comfortable using.
8. The structure is sturdy and delicate, and the whole machine adopts the Sub-components, the shell is made of light and strong ABS plastic. Beautiful appearance and simple operation.
9. The meter has an automatic shutdown function, it will automatically shut down without operating the meter for five minutes!
