**Q: For mfr: what is the accuracy, in +/-ppm, not % of scale?**
A: I'm not the manufacturer, just a buyer/owner of one these.  I can tell you what the User's Guide says about the meter's accuracy.  Quote:
Resolution: EC 0 - 00:0.1 μS / 0.01mS; 100 -999 1μS / 0.10mS; 1000 - 9990; 10 μS / 1.00mS
TDS: 0 -99: 0.1 ppm / 0.01ppt; 100-999: 1 ppm / 0.10ppt; 1000-9990: 10 ppm /1.00 ppt
Temperature: 0.1 ˚C/F
Hope that helps somewhat.
