About the product:
- The testers are built by me. Every device will be tested before shipping.
- The tester measures light, not sound.
- The tester works with mobile devices like smartphones and tablets.
It works with iOS, Anroid and Windows phone operating systems.
I do not provide any of the apps. The tester should work with any sound recorder apps or special apps for testing shutters. Free or paid. Buyers will choose the best apps for them and their devices.

-
This model is suitable for 35mm cameras and cameras that have a flat back.
Important information:
- The 1/1000th of a second tests were done with an iPad mini with the TW Recorder free app. Cheaper Android devices with cheaper electronic components, might have trouble to accurately measure speeds that fast.
- The offer is only for the testers. You will need a mobile device (smartphone or tablet) and an app. I do not endorse any mobile devices or apps.
- The tester will not work with PCs. If you want a tester that works with PCs look at my other listings.
