PH Meter, TDS PPM Meter, Soil PH Tester, PH/EC Digital Kit, 3 Pack

Worked perfectly

accurate of PPM but seems to be accurate 38 -40 PPM tap water 0-1 on distilled water -/+1 Ph digital meter is accurate to the calibration test sets with in the 0.01 +/- Does not do well with very high debris in liquid or highly oxygenated water and must sit for 5-10 minutes before accurate measurement Soil tester is iffy when compared to calibrated meters and would not fully rely on for PH in high acidity, moisture is accurately measured, light intensity also fairly accurate Would buy again and recommend to friend and family. Great value for quality.

pH meter is great when it's calibrated. I do mine every 6 months/year/whenever it seems wrong. The green thing is good for poking holes in rootbound plants. other than that. it's useless. TDS meter is great for checking your incoming tap water. mine is 200ppm. Feed levels are at 2000ppm now. Yeah.. pH and TDS/EC are necessary. The 3rd isn't.

Very useful - easy to use and read. I didn't rate the accuracy of the instruments - calibration would really need to be done in a lab. Having said that, the EC meter gave a range of comparative readings that were very useful for what I was doing. For moisture, my field assessments were consistent with the readings. An incredible package value.

PH meter wasn't very accurate as I tested it with the buffing solution they sent with it.. Within a week the PH meter was going crazy and wouldn't read properly at all.. Even if you don't have the money, just wait and get a better one.. PPM meter is still working okay, but I don't know how accurate it is seeing the PH meter. The soil PH tester seems to work okay but again I wouldn't trust it because of their other products it came with and their accuracy.. Do not get it unless you intend to just use it once!

Arrived as advertised!

CORRODED upon receipt (10-13-25). I could not remove protective cap to calibrate the yellow pH meter due to the corrosion. It’s frustrating because I was waiting to receive it in order to test the water for my young seedlings. This is the 2nd one of these yellow pH readers that I have purchased in the past 2 weeks and the first one wouldn’t calibrate properly…so I purchased another…and this time it’s corroded. I’m requesting a replacement, but if the replacement is faulty…then I would definitely not purchase this type of pH meter again. They have disappointed me thus far😢

They work

Appareil très efficace

Great products

It is good for it's price. I had a similar ph one that stopped working but it was 2 + years old. I hope this one lasts longer. Haven'ttried the soil moisture one yet but is as expected.

This product NEVER worked. No matter what, there was NO reading. Cheap gimic.

Je ne les ai pas encore utilisés. J'espère qu'ils vont bien fonctionner, malgré que je crois que j'ai reçu des articles qui ont été achetés et retournés . Surtout le testeur de sol qui va sûrement m'aider à ne pas noyer mes plantes. Je trouve que j'ai fait un bon achat
