The rotation meter is equipped with 3 high-power UVA LEDs (385 nm), which together generate a light intensity of 317 \u03bcW\/cm\u00b2 at a distance of 30 cm. The rotation meter allows the flash frequency to be set in FPM and Hz. [](https:\/\/www.pce-instruments.com\/eu\/g\/custom\/produktbilder\/uv-stroboskop-pce-les-103uv-385-skizze.webp)At the same time, it is small, handy and independent of the power supply thanks to its rechargeable battery.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<h3>Highlights<\/h3>\n<ul>\n<li>3 UVA high-power LEDs<\/li>\n<li>Wavelength: 380 &#8230; 390 nm<\/li>\n<li>Flash frequency adjustable in FPM and Hz<\/li>\n<li>Intensity: 317 \u03bcW\/cm\u00b2 at 30 cm<\/li>\n<li>Digital pulse width modulation<\/li>\n<li>Phase shift: &#8211; 360 \u00b0 &#8230; + 360 \u00b0<\/li>\n<li>Quick adjustment using x2 and \u00f72 buttons<\/li>\n<li>Intuitive control buttons and clear display<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Frequency \u2014 Measuring range: 60 &#8230; 9999,99 FPM<\/li>\n<li>Frequency \u2014 Resolution: 0,01 FPM<\/li>\n<li>Frequency \u2014 Accuracy: \u00b10.003 % of the setting or \u00b11 LSD<\/li>\n<li>Frequency \u2014 Measuring range: 10000 &#8230; 300000 FPM<\/li>\n<li>Frequency \u2014 Resolution: 0,1 FPM<\/li>\n<li>Frequency \u2014 Accuracy: \u00b10.003 % of the setting or \u00b11 LSD<\/li>\n<li>Frequency \u2014 Measuring range: 1 &#8230; 5000 Hz<\/li>\n<li>Frequency \u2014 Resolution: 0,01 Hz<\/li>\n<li>Frequency \u2014 Accuracy: \u00b10.003 % of the setting or \u00b11 LSD<\/li>\n<li>General technical data \u2014 Display type: LC colour display<\/li>\n<li>General technical data \u2014 Display size: 2,8 Inch<\/li>\n<li>Storage medium Internal memory: Operating time 4,5 h<\/li>\n<li>Storage medium Internal memory: Operating time additional information at flash frequency 100 Hz, 1 %, display brightness 70 %<\/li>\n<li>Storage medium Internal memory: Automatic power-off from&#8230;to 2 &#8230; 10 min.<\/li>\n<li>Storage medium Internal memory: Luminous intensity 635 \u03bcW\/cm2 @ 20 cm @ 1000 Hz, 1%<\/li>\n<li>Storage medium Internal memory: 317 \u03bcW\/cm2 @ 30 cm @ 1000 Hz, 1%<\/li>\n<li>Storage medium Internal memory: 115 \u03bcW\/cm2 @ 50 cm @ 1000 Hz, 1 %<\/li>\n<li>Storage medium Internal memory: Light colour UV light (380 &#8230; 390 nm)<\/li>\n<li>Storage medium Internal memory: Phase shift-360 &#8230; 360 \u00b0<\/li>\n<li>Storage medium Internal memory: Pulse width 0.01 &#8230; 1 % of pulse duration<\/li>\n<li>Storage medium Internal memory \u2014 Resolution: : 0.01 %<\/li>\n<li>Storage medium Internal memory: 0.01 \u00ba &#8230; 3.60 \u00ba of 360 \u00ba<\/li>\n<li>Storage medium Internal memory \u2014 Resolution: : 0.01 \u00ba<\/li>\n<li>Storage medium Internal memory \u2014 Menu language: Turkish, English, Polish, Spanish, German, Chinese, Russian, French, Italian, Dutch<\/li>\n<li>Storage medium Internal memory \u2014 Protection class (device): IP52<\/li>\n<li>Storage medium Internal memory \u2014 Power supply: 5V DC, 2A<\/li>\n<li>Storage medium Internal memory \u2014 (Rechargeable) battery: 1 x 7,4 V DST604665 , Lithium-ion battery<\/li>\n<li>Storage medium Internal memory \u2014 Capacity: 2200 mAh<\/li>\n<li>Storage medium Internal memory: Performance 16,28 Wh<\/li>\n<li>Storage medium Internal memory \u2014 Operating conditions: -20 &#8230; 60 \u00b0C , 35 &#8230; 85 % RH<\/li>\n<li>Storage medium Internal memory \u2014 Storage conditions: -20 &#8230; 60 \u00b0C , 35 &#8230; 85 % RH<\/li>\n<li>Storage medium Internal memory \u2014 Dimensions: ( L x W x H )165 x 90 x 35 mm<\/li>\n<li>Storage medium Internal memory \u2014 Weight: 284 g<\/li>\n<\/ul>\n<h3>Delivery scope<\/h3>\n<ul>\n<li>1 x Rotation Meter PCE-LES 103UV-385<\/li>\n<li>1 x USB-C cable<\/li>\n<li>1 x Quick Start Guide<\/li>\n<li>1 x Service bag<\/li>\n<\/ul>\n<h3>Documents<\/h3>\n<ul>\n<li><a href=\"https:\/\/pim.pce-service.net\/upload\/files\/assets\/pce-instruments-e6576cac396eba5b5.pdf\">Supplier document<\/a><\/li>\n<li><a href=\"https:\/\/pim.pce-service.net\/upload\/files\/assets\/pce-instruments-u662a17473478e510.pdf\">Supplier document<\/a><\/li>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=5793343&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Rotation Meter with 3 UVA high-power LEDs (385 nm) \/ 317 \u03bcW\/cm\u00b2 at 30 cm \/ pulse width in per cent, degrees or time adjustable \/ phase shift \/ simple, clear display \/ mains-independent thanks to battery operation.
