HMDCOM100 Waterproof EC/TDS And Amp Temperature Combo Meter

HMDCOM100 Waterproof EC/TDS And Amp Temperature Combo Meter

Q: Can this unit be used to test PH?

FROM HM DIGITAL: The COM-100 is NOT a pH meter. It measures EC (electrical conductivity), TDS (total dissolved solids) and temperature. For pH, please purchase HM Digital's PH-200. For more information, please visit www.tdsmeter.com

Q: My meter want read over 999 or am I looking at the wrong ppm?

Select 442 scale. Your meter will read more than 999 ppm.

Q: Any trouble measuring in mS?

FROM HM-DIGITAL: The COM-100 is a professional waterproof EC/TDS meter that has three EC-TDS conversion factors and selectable modes allowing you to measure in the µs, mS, ppm and ppt scales. For more information, please visit, www.tdsmeter.com/products/com100.html

Q: Isn't one supposed to use calibrating and cleaning solution with this?

I clean mine with a wet Q-tip. There is a TDS calibration solution I use when I recalibrate every month.
