Packing List
| photoelectricity/Contact tachometer |
| Specification and model： | DT-2859 |
| Product application： | Used to measure the speed of motor、Linear velocity or frequency；Widely used in motor、Electric fan、papermaking、Plastic、chemical fiber、、automobile、aircraft、Shipbuilding and other manufacturing industries。 |
One meter for multiple purposes。oneplatformThe instrument can be used asphotoelectricitytypespeedsurface，Non contact speed measurement（r / min）；It can also be used asContact tachometerconductspeedandLinear velocitymeasure( m / min , ft / min )Contact measurement of metal。Frequency can also be measured，cycle，Number of pulses，Pulse distance，customPulse distanceetc.。
*digital display，Parallax free。
*Wide measurement range，High resolution。
*Automatic memory of large values during measurement、Small value and one measurement。
*Strong structure、delicate，be easy to carry about。The whole machine adopts durable advanced electronic components；The shell is light and hardABSPlastic，Beautiful appearance，Easy to use。
