Easy to use shutter speed tester for 35mm film cameras, able to measure shutter speeds up to 1/2000 sec with max error at 8% at 1/2000 shutter speed. For 1/1000 max error is 4% and so on for other shutter speeds.

   It has 3 sensors for measuring frame exposure unevenness. Sensors are located diagonally across the frame, so you can use it for vertical and horizontal shutter movement systems. 

      This tester need bright light source (not included) to be able to take measurements. You can use a flashlight or lamp as a light source. It happens that the light use PWM to regulate its brightness. Basically, it means, that light is flickering. Such light won't be good for shutter speed measurements. The tester has a mode to detect such light. Please refer to article in getting started guide, chapter "Testing light for flickering": https://drive.google.com/file/d/1qgurbE2kzCGoxPpAp-NJlor57iggEX-O.

   Device has OLED screen of 0.96", only one button and simple screen menu, so it's straightforward and easy to use.  

   It's USB powered (Type-C), no batteries needed. You can use your phone/tablet power adapter, power bank or your PC to power the device. Power specs: DC 5V, 20mA. 

   This device is designed and made by me, case is printed on a 3D printer with PLA plastic. Every device is tested after production.
