pH EC Meter for Water Hydroponics PPM and pH Meter for Nutrients Measure pH PPM Conductivity Temperature DWC PH and EC PPM Water Tester for Nutrient Solution EC pH TDS Meter for Water System

Very accurate and amazing price. Works just as well as my Apera. I dont even use the Apera anymore. This has both displays on 1 screen. But the battery life isnt the best. Better stock up!

It all depends on what your looking for , I was using a hand held measuring device but was really a pain to add/subtract nutrients now it’s right in front of me , no fuss no muss add subtract nutrients just by watching control measurements

Good Meter. Good repeatability.

Finally, I found a meter that ACCURATELY measures water pH! This pH meter is easy to calibrate and provides accurate pH readings that I find essential to growing blueberries, strawberries and blackberries. This meter was affordable and provided good calibration and use instructions. I love it!

haven't used yet so honestly not sure if works properly or not. my problem is getting hold of someone who knows about devices and it's instructions. in plain black and white print it tells you how to calibrate TDS/PPM using 2 solutions. 1st no solutions in box and it doesn't list. BUT THE INSTRUCTIONS SAY TO USE 2 SOLUTIONS TO CALIBRATE TDS. so I contact seller (I think) through Amazon because i emailed company on box and they gave me some bs about being just in control overseas shipping. whatever that means. through the Amazon product questions thing and it said instructions say NOTHING about calibrating TDS/PPM. WHAT??? it's a freaking EC/TDS (4-1) meter!!

Too good to be true. I remember these costing a crazy amount in the past. Top quality, calibrated super easy, accurate, perfect function. Easy to use. Intuitive. I use if for plant nutrient watering for rare succulents and the results are super good. No guess work anymore. Crazy value here.

Muy bueno actualmente lo uso todos los días varias veces ya que soy agricultor. Lo recomiendo muy facil para calibrar.

This tester isn't much more expensive than previous I've purchased, but is so much better. The previous models I have purchased needed constant recalibration, while this one doesn't. I still check for accuracy before every test, it's just nice to not have to recalibrate with every use.

This water quality tester provides all the data that I need to monitor my hydroponic gardens: pH, EC, and temperature. I appreciate that the package includes the buffer powder to calibrate the pH. The instructions are easy to follow. As far as I can tell, the tester seems to be accurate. The pH readings are consistent with the results of my pH test strips. I can't validate the EC readings, but they seem reasonable based on the amount of nutrients added. I hope the batteries will last a long time.

It worked for 3 months. I was able to calibrate and it was accurate. After 3 months it is way off and won’t recalibrate. I put it in the included 7.0 buffer and it always calibrates to 10.0. The 4.0 buffer will only calibrate to 7.0. I tried using new buffer solutions only to get the same result. I have been trying to get an email contact from the seller but can’t find it on amazon. In the box it says they will replace up to one year but on amazon it says on month only. I can’t seem to get any support or solution
