If my memory serves, Fluke came out with something equivalent back in the (early) 1980s. That said, I've never known anyone to actually use one. I suspect there's a reason for that, though I honestly don't know what that is. As for me, I've never seen a need. We use it in industrial senoring applications to check the performance of sensors mounted in a silo, where there is no mains woltage. More, these sensors are capacitively referenced to protection earth and must not see an additional connection to earth during the measurement. Believe me, having used it once you want never miss it!
