No, it test for TDS in PPM (parts per million). The reading is taken from the EC reading and converted within the unit to TDS. This is the accumulation of all dissolved solids in your water. But what conversion factor is used by this company? A 5.0 conversion will have different reading than one with a 7.1 conversion factor. Makes a difference. Learning to read EC is best option along with a tester that reads EC and PPM. No calibration on some. To test your pH you can use the paper strips, General Hydroponics sells a pH Test Kit that includes testing solution along with pH Up and pH down for adjusting your pH to your requirements if you are into gardening. Very fast and easy to use. There are a number of pH test pens on the market. Most need calibration and calibration solutions that is a consumable. There are different calibration factors on these as well. But easier to use and more accurate once you learn it.

Q: What is the accuracy of this tester?

Can’t say for sure. Howerver, the first time I used it, the number I was getting from an old RO membrane were 350ish. I thought for sure the meter was in error. I then opened a bottle of filtered water and tested that. The bottled water reading was 12 so I think the meter is very accurate. I have since replaced the RO membrane and my numbers are in the high 20s to low 30s. I hope this helps. I would highly recommend this tester - it’s a great buy.

Q: Is there a minimum amount of water that can be tested?

I just put some water in a cup and put end of TDS gauge in, no more than inch. By the way, the best water will test 0. I use a zero water pitcher. I use this to check if new filter is needed. I hope this helped you.

Q: At what reading should the filter/cartridge be changed?

Your filter and cartridge should be change every 30 days , if your ppm reading over 300 you may need do some water change , also test for nitrite , nitrate and ammonia . under 300 ppm you are OK , should be around 150 ppm to 250 ppm , but not over 400 ppm . usually do 10% water change every month or twice a month depend on how many fishes or shrimps you have. Hope will help.
