High-precision Infrared Laser Contact Tachometer Measuring Instrument

High-precision Infrared Laser Contact Tachometer Measuring Instrument Features: 1.Non-contact using photoelectric technology design, for some fast and its can not be measured objects to detect, such as fans, motors, engines, aircraft, propellers, cars, etc., before using the reflective stickers (included with the product) to the object to be measured after running can be detected.2. Contact to enable reliable contact between the tachometer and the measured shaft The tachometer is equipped with different contact heads (measuring line speed contact head, tacho contact head), which can be installed on the tachometer input shaft according to the object to be measured.3. With automatic memory function, the upper limit, lower limit and last value of the data can be recorded at any time, and the test results can be produced in 1 second on average.4. The battery can be replaced by yourself, or the shop to buy the corresponding charging device, long service life, if you do not understand the st
