The answer is, "Maybe they're really more expensive than we are."
Teletek: 100% guaranteed satisfaction. Period.
Please note the pictures: the first shows a 1.000000 volt input to the divider which is set to .2222, output shown on meter is .222205. Second setting is 0.5555 with its output being .555502, and the third setting is .8888 with an output of .888802, all within 5 parts per million.
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.
