PH Meter, Digital 4-in-1 PH ORP H2 Temp Meter with ATC, H2 Water PPB/PPM Meter, 0.01 Resolution High Accuracy PH Tester for Drinking Water

This PH digital meter is necessary and easy to use. It’s very important to know the quality of the water we’re drinking, cooking with, and bathing in. Testing the water’s PH will determine if the water is alkaline and safe and healthy or acidic and unhealthy toxic. It’s very important to know, so, we can decide if it’s safe and clean and healthy to drink, cook, and bathe in. It’s a great important device to have. I highly recommend it.

ORP meter does not work. Would not buy. PH meter works fine

The media could not be loaded. I wanted a pH meter for home to help introduce science concepts to my kid and for the occasional measurement of something related to plants. We have basic soil and have been adding amendments to raise the pH so nutrients are available. I wanted to measure the progress along the way by adding distilled water to soil samples. Being a little naive, I was first shocked that readings of distilled water didn't jump to pH 7. With a little reading, I figured out that distilled water has no ions. So while it's technically pH 7, the meter needs ions to get a reading. So in ionically weak solutions the readings can vary. I used the calibration pouches, and the factory settings were very close (within 0.1 to 0.2 units). Having done that little proof for my own confidence, I'm really happy with the results I'm getting, and I just might be measuring things from the fridge and cabinets for fun. Remember to rinse your pH meter with distilled water after use to avoid damaging the probes. The glass bead is apparently for the thermometer, so make sure to not smack it too hard.

Will be returning because I have no way to use the ppm setting on this meter . Why offer it as such and nothing works

I've been using this in my pool, and it worked well for the first two weeks. However, now the pH levels always read about 9. I have a Taylor 2006 pool kit, and the results from this device are not accurate in comparison. I also use a similar device that checks pH and salt levels, which has been accurate. I'm going to try recalibrating the device again and will report the results.Pros:- Easy to use- Save money on buying test strips- I've had this a short time, but the battery hasn't died within a month time.Cons:- Takes about 30 to 45 seconds to show the final result.- Requires recalibration within two weeks of receiving it or may not work properly

Although this device can also be used to test ORP (Oxidation-Reduction Potential) /H2 (Hydrogen), I focused on testing the pH level of my pool.**Unless you already have experience with a device like this I highly recommend reading the instructions completely. It's not a big booklet and it's well-written. **In the first picture are the contents of the box. There are four packets of powder with different pH levels. KEEP THEM. They are for calibrating (or re-calibrating) the tester if needed at a later time.Having said that, the instructions state that the tester is factory-calibrated.The next pictures show the top (with cap unscrewed) showing the battery compartment. (Batteries are already installed). The picture of the bottom shows the electrodes / probe that go into the water. Note: there is a GLASS bulb and you need to use care when placing the probe into the water.Do NOT let the water go above the blue ring. (Which actually unscrews so you can replace the probe if needed).I turned the device on and then pressed the "Mode/Cal" button in order to select pH. (There are other options, as well).I filled a measuring cup with pool water and lowered the probe into it, being careful not to let water reach the blue ring. Sorry for the shadows and reflection of my phone. But you can easily see that there is a pH reading of 7.62, which is within proper range to help prevent algae growth and promote comfort.After doing the test, I rinsed the probe section with distilled water and placed it on the counter (leaving the cap off) to dry. The instructions are clear on this step: you need to carefully rinse the probe components after each use to maintain accurate readings.This is a great little product and I'm glad I have it!

I got this to test my water. It's pretty complicated and I still have not figured out how to use it. I've read the instructions but still don't understand it. It may just be me.

I recently bought a hydrogen bottle but had not tested the hydrogen level yet.Tried this PH meter. Not sure if it was accurate because I had no other meter to verify the readings.This meter measure the PH of the provided samples accurately, so I assume the hydrogen readings are also accurate.Well constructed and requires 3 button cells (which it comes with). Will continue to test with other samples.I highly recommend it.
