I knew my tap water was good but its very good 59ppm out of the tap not bad. So it keeps my fish tanks in the safe range for my dwarf shrimp. I LOVE that I can get a good read on my tanks Temps. That was a big selling point for me. I not sure when I will have go calibrate it but it should not be hard to do. So far straight out of the box it's been great. I recommend this TDS metter for fish keepers.

Handy Gadget My salt pool does not have a display for salt concentration so I bought this one. The first one I ordered did not work. I went online and Amazon replaced it right away. I had to recalibrate the second instrument myself. It was off. I put a 1/2 tsp of salt in .5 liters of water, thereby making a 6000 ppm solution. I calibrated the device by turning the screw in the back until it read 600 x 10. I went to the pool store where they calibrated their own solution at 3000 ppm. When I used my newly calibrated meter it read 300 x 10, indicating I calibrated it correctly and it is an accurate instrument. It is a great tool for the money. It's too bad it doesn't measure temperature in Fahrenheit. I don't use Celsius and cannot readily convert.
