A high coefficient of pulsation can affect fatigue, well-being and eye strain. The application allows you to measure the ripple coefficient of radiation sources in the visible spectrum: - LED, halogen, fluorescent lamps and incandescent lamps - various lamps - LCD and LED monitors and TVs The readings are not 100% reliable and the average error depending on the light source and the frequency of pulsation can be more than 10%. In order to take measurements, you need to bring the phone to the measured source and press the start button. The measurement results will be updated in real time, the arrow will show the ripple factor, and the scale will be filled from green to red. For best results, keep your phone straight. If the phone is not fixed, an image of the shaking device will appear in the lower left corner of the screen and the readings will be very different from the actual ones. ## Illuminance Pulsation Meter Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/0a/85/a0/0a85a08e-d1b9-261c-92b4-632acc0deec8/pr_source.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/dd/c0/b8/ddc0b8a0-9375-7ec0-cbc3-df0613a74435/pr_source.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/3c/ba/52/3cba52d7-a3ea-0739-20dd-633bc6a32cc6/pr_source.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/a0/46/36/a0463678-dc91-291f-b6cb-ccb677bf72d7/pr_source.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/2c/cd/fe/2ccdfeb0-4353-e2e1-b93e-7cdb7ffe9b04/pr_source.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/51/15/b4/5115b4b9-939a-e674-1ace-0bad7a60581e/pr_source.png/1242x2688.png) ## Illuminance Pulsation Meter Rating Breakdown in United States - 5 stars: 19 (59%) - 4 stars: 6 (19%) - 3 stars: 2 (6%) - 2 stars: 3 (9%) - 1 stars: 2 (6%) ## Illuminance Pulsation Meter Reviews in United States ### ****- "Good app with lots of potential" Can only measure frequencies up to 100hz. Would love to see some more advanced frequency counting or use of the slow motion camera to measure higher frequencies. The onboarding process is a bit much, could probably simplify that as using the app is very straight forward. -- Travis Underhill, 2023-11-24 ### **--- "Not clear what it does" It outputs a number from 0 to 100. What does it mean? Main frequency? Intensity? Something else? -- Stepa Me, 2023-01-14 ### **--- "Background information" I like the app but not totally sure what it is telling me. More strobing is bad I’m sure but more info on what should I be thinking about doing based on the readings I’m getting? -- AndrewZ60, 2020-02-03 ### **--- "Confused" You say the average error percentage could be greater than 10%. Is there an upper limit? I am testing a flicker free light bulb and i her a reading of 38%. -- khanna111, 2019-12-09 ### ***** "Finally, one that works" I use this for my work to easily identify LED’s that are flickering. I can check one hundred LED’s in under one minute whereas before it took several minutes. A great utility. -- TJ Lucero, 2019-11-09 ### ***** "Great app!" I use this app to tell me if my light bulbs, computer monitors, and TVs are junk or not. This app is easy to use. Most monitors are flicker-free, but most LED lightbulbs are not. I would love it if the developer could provide even more information about this topic. This app is well worth the money. Protect your eyes and health. -- kerplunknet, 2019-10-16 [View all Illuminance Pulsation Meter reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Illuminance Pulsation Meter Available In -
