I recently purchase the PC60 to test my aquariums (freshwater fish and shrimp) to monitor the PH and EC (TDS). The unit was sold as Used but it is like new condition. It contained all calibration solutions and they were in sealed bottles and all other standard extras were included. Love the case to keep all of the components together and to keep the tester from getting damage. As recommended in instructions, I soaked the PH probe in the solutions for about 24 hours. Next I checked the PH calibration and it was within .03 so I did not need to calibrate the PH. Checked the EC and it needed to be calibrated. This was so easy. As a comparison, I have a cheap TDS meter and when I tried to calibrate it, I was unsuccessful because who knows what a mini phillips screwdriver is? The push button calibration is simple and easy. Test result were more believable than my other meters and API drop test kits. Since my drop test only goes down to 6, I was not sure exactly how low my PH was and who can ever exactly know which shade of green matches the vial? Now I know more precise numbers. TDS is calculated by the tester and this tester gives you the ability to change the conversion factor. Great option but I am struggling with determining an accurate conversion factor for my application. (This is not a fault of the tester) All information I can find on the dwarf freshwater shrimp I keep has their ideal PH, GH, KH, and TDS. Since TDS is actually calculated off of the EC, I am not sure what conversion factor I should use, but I settled on .48 because I have some 342 ppm calibration solution which is also 700 microseimens, so simple math 342/700=0.488. I know a lot depends on what you testing for the conversion factor. I wish the "shrimp experts" would provide an ideal EC, since that is the basis in which TDS is calculated. Again, not a fault of the PC60, its a plus to be able to change the conversion factor. Biggest issue with shrimp is consistency so I am hoping that this meter will help me to keep the parameters more consistent. Bottom line - Awesome tester for PH, EC, TDS, Salinity, and Temperature. I did not find any other combo testers on the market for this price. If you buy a nice EC and PH pen tester, you will spend well over what this tester cost and I don't think they come with the case and calibration solutions.Read full review

Excellent pool meter, works very well, calibrates easily. Need to get more storage solution (should be distilled water). Waterproof and it floats, easy to read, follow instructions for use and calibration and you will have no problems.
