Portable Digital Photo Tachometer with a laser pointer is designed for precise noncontact measuring of rotary speed in units difficult to access, as well as for measuring of shaft angular velocity.
Features
It is used the microcomputer (CPU) technique and junction laser technique for one instrument combine PHOTO TACH. (RPM) & CONTACT TACH (RPM, m/min).
Wide measuring range and high resolution.
Yellow green backlight makes sure that tachometer can work normally in any light circumstance.
The last displayed value/max. Value/min. Value maybe automatically stored in memory and 96s of measured value continuously.
So this makes customers collected and recorded data. (The tachometer starts to store the data measured after which is renovation for three times).
The tachometer can be connected 6V direct current stable voltage power in favor of using for long time.
Low battery voltage indication.
Contact part and photo part can be switched value at any time.
New surface speed sensor with flute vials to measure speed and length of wire, cable and rope conveniently.
The instrument is delicate and rugged. It uses the durable, long-lasting components and a strong, light weight ABC plastic housing. The comfortably in either hand.
