PCE Instruments PCE-LES 103UV-385 Rotation Meter with 3 UVA High-Power LEDs (385 nm)
- Part #:PCE-LES 103UV-385
- Condition:Brand New






Rotation Meter with 3 UVA high-power LEDs (385 nm) / 317 μW/cm² at 30 cm / pulse width in per cent, degrees or time adjustable / phase shift / simple, clear display / mains-independent thanks to battery operation
Motion analysis of rotating machines is quick and easy with rotation meter. The rotation meter is equipped with 3 high-power UVA LEDs (385 nm), which together generate a light intensity of 317 μW/cm² at a distance of 30 cm. The rotation meter allows the flash frequency to be set in FPM and Hz. At the same time, it is small, handy and independent of the power supply thanks to its rechargeable battery.
The rotation meter is operated intuitively using 10 buttons, allowing quick settings to be made. The observation point can be variably shifted using the phase shift. The pulse width can be used to set the duration and therefore also the intensity of the flash frequency. In the settings menu, you can select the display brightness and switch off the display after a period of inactivity, which extends the battery life. The rotation meter is supplied with a USB-C charging cable in a service bag.
Rotation Meters are indispensable tools for monitoring and inspecting production facilities, e.g. in the printing and textile industries. But also for general maintenance and inspection tasks in all industrial sectors. They also enable non-contact speed and vibration measurement: if the flash frequency of the rotation meter matches the movement frequency, the measured object appears stationary.
