Low range TDS meter?

[NatureNerd]

Does anyone know of a TDS meter with an appropriate range for high quality RODI water? Most of the units for sale seem designed for high range readings. It would be far more useful to have a range of 0-10 or even 0-100 rather than the 0-999 units that seem to be the only option. Am I missing something here? Does any vendor sell one of these? Resolution and absolute accuracy just aren't there with so much range.

No, that appears to have a range of 0-8000 ppm, or so. With auto range and a one percent accuracy, a reading of 0 could be easily 1 or 2 ppm. Perhaps it isn't needed, but I was looking for something that could give me 0.1 resolution in the range of 0-10 ppm.

The COM100 does that.
