PCE Instruments PCE-LES 103UV-365 Rotation Meter with 3 UVA High-Power LEDs (365 nm)
- Part #:PCE-LES 103UV-365
- Condition:Brand New






Tachometer with 3 UVA high-power LEDs / 202 μW/cm² at 30 cm / pulse width in per cent, degrees or time / phase shift / simple, clear display / mains-independent thanks to battery operation
Motion analysis of rotating machines is quick and easy with tachometer. The tachometer is equipped with 3 UVA high-power LEDs, which together generate a light intensity of 202 μW/cm² at a distance of 30 cm. With the tachometer, you can set the flash frequency in both FPM and Hz. It is also small, handy and mains-independent thanks to the rechargeable battery.
The tachometer is operated intuitively using the 10 buttons, allowing quick adjustments to be made. The phase shift allows the observation point to be moved variably. The pulse width can be used to set the duration and therefore also the intensity of the flash frequency. The display brightness can be selected in the settings menu and the display can also be switched off after a period of inactivity, which extends the battery life. The tachometer is supplied with a USB-C charging cable in a service bag.
Tachometers 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 tachometer matches the movement frequency, the measured object appears stationary.
