Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Moisture & pH Meters
Having worked in the calibration industry for years, I can say that the construction, accuracy and repeatability of both pH and ppm meters are worth their weight in gold. If both units are well taken care of, and the proper calibrations and verification's are performed on a regular basis they will outlast their overly engineered, overly priced counterparts. Just ensure that your certified calibration standards/solutions are utilized correctly in conjunction with manufacturer's calibration procedures.

For the price paid both these items work well. Calibration is holding well on the Ph meter. The TDS meter appears solid also as far as calibration.

pH meter is pretty accurate for the price. TDS meter works fine, except for one minor hiccup where it refused to show a reading. Next day, all was fine again.
