VIVOSUN TDS Tester 3-in-1 TDS EC & Temperature Meter Ultrahigh Accuracy Digital Water Quality TDS Tester (Blue)

Works great! Price was awesome! Really fast shipping. Thanks so much!

Its is as described and works as described and cost almost nothing. I cant complain about a thing. 5 of 5 I payed $9.99

This gauge was just what I needed. I used it to determine how salty my water was after going through a water softener. I did not realize how salty those things make your water.

The most inaccurate low budget ppm meter I’ve ever used, and believe me I’ve used a lot of these cheap things. This one will be reading 1811 ppm. Take it out of the water, tap it on the wall bc I know what it’s reading is not accurate. Put the ppm meter back in the water after a solid wall tap, reads 1934. Thanks, 80 ppm monopotassium phosphate over my target number because this thing is a POS. Don’t buy it. I, as a broke ass individual, is telling you it’s worth it to own the bluelabs meter. Not the stick one, but the one with the probes on cords attached to the display. I hope this helps someone not only save $8 or $11 or whatever this pos costs.

If you're okay with trusting that your $10 purchase has been calibrated properly, and you're willing to toss caution to the wind for your entire grow... yeah i mean i don't know what i was expecting for $10 honestly lol. You can't calibrate it, and it's pretty common knowledge that they need adjusting from time to time. Good for a cheap, temporary tester, assuming yours is calibrated properly. EDIT: Tested on 10ppm solution and it's spot on. My concern is how long will it stay accurate?

Needed a new TDS meter as the previous one I had started going faulty, and this appears to be the superior choice. For price it's a great deal, very accurate readings and exactly what I needed to make sure the water I am filtering is actually getting filtered as needed.

Some personal advice spend the money for a better TDS EC meter. They are garbage out of the three that were bought ,myself and two friends two out of the 3 will not calibrate because the buttons don’t work properly. THEY DO NOT COME CALIBRATED. The third one would calibrate, but would only stay calibrated for about a week, do not waste your time with this product. It has cheap components and is not worth the stress if you’re going to use an ECTDS meter spend the money don’t be cheap. I did that and I’m regretting it tremendously. Here’s a picture of what happens 16 days with a junk TDS EC meter? I don’t fully blame the meter I blame myself for being stupid enough to buy something for $13. I would say if you’re serious into hydroponics, don’t take the cheap route.

AFAIK it is accurate, seems sensitive. Fresh distilled water read zero, after using that to clean of ph meter a few times the meter read 17. Water runoff was 9724.

This is my 2nd buy of this model My first one still worked great but I gave it to a friend and bought another I love gardening and my annual flowers The fertilizer I use is excellent and i use the EC meter option for this Excellent meter
