Tadeto Soil pH Tester, High Accuracy Digital pH Meter for Soil, Garden, Water, Plants, Solution and Food, Soil pH Test Kit with Thermometer LCD Display, Calibration Powder and Alloy Protective Cap

I purchased this device in May of 2025. I use this in my worm farm. So far so good. Is it accurate? My worms are thriving and doing well.

Works Bentham my Bluelab which shocked me

I purchased this meter to help me really dial in my cannabis garden. I wasn’t having any problems, but having another tool at hand couldn’t hurt. I received the meter and after unpacking I calibrated it. Fairly easy to do, instructions were a little confusing at first but figured it out quickly. The readout on the meter was not working properly, did not show complete numbers . Only half of the screen showed numbers. Took out the batteries, reinserted them, pushing buttons at random, no go to get it working properly. Sent it back, and 5 days later I received a new one. This one worked great. Readout works, holds its calibration pretty well and is nice and durable. I’m not sure how precise this meter is quite yet, but am working on that right now. But seems fairly accurate. All in all, I’m pleased with the meter and would recommend it.

After using Oakton for a couple of decades which were perfect, plus one or two Hannah ones that were junk, I was very impressed by this Tadeto which ticked all the boxes for me, price, 3 pt calibration, back light, large display, screw tight cap that hold storage solution, a few pouches of calibration crystals, and basically waterproof. My unit was dead on accurate out of the box just like someone else mentioned, and it came with the cap full of storage solution to keep the probe in perfect condition (unlike Oakton). The soil probe/guard was a terrific addition for people who really want to know what's happening in their soil. It turns out in California with all the calcium carbonate in the municipal water supply that my 8.3 pH tap water was leaving my soil up around 7.5 pH, not good. I watered a few times with Neptune's Harvest fish hydrolysate which brought things back down closer to 6.0, and the plants loved it. The value here is tremendous.

I wanted to like this meter, but unfortunately, mine has a firmware or display defect that makes it impossible to trust. The Problem: According to the manual, during calibration the meter should display: CAL1: 4.01 CAL2: 7.00 CAL3: 10.01 However, my unit shows: CAL1: 4.1 (not 4.01 or even 4.0) CAL2: 6.7 (not 7.00 or 6.9) CAL3: Correct This is not a rounding issue—4.01 rounds to 4.0, and 6.86 (if using NIST standard) rounds to 6.9. The numbers displayed do not match any standard buffer table or the manual. Why It Matters: Even if the actual measurements are accurate, the calibration prompts are wrong. You should not have to guess whether to trust the screen or the solution. A pH meter needs to be reliable, and this one isn’t right out of the box. Verdict: Defective unit or badly design firmware. I am returning it.

Suit my liking, works well

Works great!!! Don’t spend extra money on Blue Labs or Apera this does the exact same thing at a fraction of the cost. I’m glad I listened to another person that said the same thing as he tested multiple meters side by side. I always prefer to spend a bit extra to know I’m getting a quality product especially when it comes to parameter tools but there was absolutely no need in this case. Comes with a nice zip up bag, multiple calibration packets, KCI liquid for the probe, batteries, brush etc. 10/10 in my books

Works well when you put the batteries in the right way. The symbols on the unit are a little backwards from what you normally see. So far no issues

Bon rapport qualité prix. En entrée de gamme (Moyenne ?) il est parfait.

El medidor va muy bien, llega bien empaquetado y no uno, sino dos sobre por cada solución de calibración! Estoy muy contento con la compra

Cercavo un pH di qualità migliore rispetto alle solite cinesate e devo dire che funziona molto bene

Gutes Produkt! Kam in einer passenden Schutzverpackung an und war vorkalibriert. Habe es mit den beigefügten PH Proben dennoch problemlos kalibriert und habe seitdem gute Ergebnisse. Klare Empfehlung ! Habe es bisher für meine Sauerteige aber auch im Garten für Pflanzen verwendet.
