Yes, the testers with the eye tubes check leakage at high voltage. I have a Heathkit one ( an IT-11) which applies up to 600 VDC to check for leakage. It also comes in handy for reforming electrolytics which have been sitting idle for a long time.
The IT-11 I have comes up regularly on ebay, selling for $30- $40.
