PulseHPT is a 3-in-1 shutter speed tester #Photography

PulseHPT is a compact shutter speed tester for vintage cameras. Quick and easy measurement via Hot Shoe or PC socket. As well as accurate though-the-lens testing with light sensor. Ideal for in-the-field testing of unknown cameras.

When taking a photo, the flash sync signal activates, and remains active until shutter is closed. Thus the approximate shutter speed can be measured.
