HR-6800 Handheld Digital Tachometers From ONO SOKKI

 

CE marking

HR-6800, Handheld, Digital, Tachometers, ONO SOKKI

The HR-6800 is a non-contact type handheld digital tachometer, which can measure the high speed rotational speed at Max. 999,990 r/min with high accuracy.

In addition to the objects such as the dental hand piece or yarn texturizing machine, the non-contact rotational speed measurement of the high-speed cutting drill or high-speed motor itself is simply possible with direct reading at the unit of r/min by closing the magnetic-electro detector with magnetizing the rotated object or figure of the drill.

Wide range of the rotational speed measurement is possible from 100 r/min to 999,990 r/min. Not only analogue output (switch-able to monitor output signal) but also the pulse output signal are provided as standard.

Analogue signal can be used as recording signal to data recorder and so on. Monitor signal can be used in order to check the signal waveform or to be analyzed by FFT analyzer. Further, pulse signal can be input to FFT analyzer as external sampling signal of tracking analysis.

The measurement result can be memorized into internal memory at Max. 20 data, which is convenient for check and recording after the measurement.

 

Features

  • High-speed rotation measurement from 100 to 999,990 r/min

  • Built-in memory function Up to a maximum of 20 data can be saved to memory.

  • Both analog and pulse outputs provided as standard.  Used for recording rotational speeds and as rotation synchronization signals

  • Built-in peak hold function - The maximum and minimum values can be displayed during measurement.

  • Large LCD with backlight
