This is the best voltage divider ESI ever made, with 7 digits of resolution.
It has seen only laboratory usage-the interior of this item is very clean with no signs of overvoltage. Its input resistance is 100,000 ohms, not 10,000 ohms as with some cheaper voltage dividers, and as much as 700 volts may be safely applied to its input.
