Lantai photoelectric/contact tachometer linear speedometer DT2858
*One table for multiple purposes
Product details
*One table is versatile. One instrument can be used as a photoelectric tachometer for non-contact speed measurement (r/min); It can also be used as a contact type tachometer for measuring rotational speed and linear velocity (m/min, ft/min) through contact measurement.
*Digital display, no parallax.
*Wide measurement range and high resolution.
*Automatically memorize the maximum value, minimum value, and the last measurement value during the measurement period.
*The structure is sturdy, exquisite, and easy to carry. The whole machine adopts durable advanced electronic components; The shell is made of lightweight and hard ABS plastic, which has a beautiful and elegant appearance and is easy to use.
