[Mini Size]The mini size ph tester water we designed allows you to easily put it in your pocket, so you can take measurements anytime, anywhere.The digital water tester can help you test it whether you take it to the pool, on a trip, to the beach or camping.
[Family Essentials]As a tool to improve the quality of life. the water ph tester can be used to test drinking water, swimming pools, PH balance in aquarium, RO system, spa or hydroponics growing system. Basically all the environments that need to test pH value can use this tester to get accurate data.
[Easy to use]The water quality tester is very easy to operate.Turn on the switch,put the probe into the water and stir (make the small glass ball fully contact the liquid) and the value can be read when the value is stable.The backlight design allows you to easily read even in dark conditions.
[Automatic temperature compensation]There is no need to care about the temperature of the liquid being measured. The ph test kit has an automatic temperature compensation function, which can be adjusted according to the water temperature and water quality.
[Friendly reminder]Regularly cleaning your pH meter electrode is crucial for ensuring accurate data. Contamination of the electrode can lead to unstable measurements. Please use the appropriate cleaning solution. If you have any questions, feel free to reach out to our customer service.

Simple to use
I use this pH meter to measure the pH level in my fish tank. It provides fast and stable readings, and the operation is very simple. It helps me monitor water quality in a timely manner. This pH meter is an absolute must-have tool for pet fish ownersâ highly recommend it!

Not as accurate as it says, but accurate enough for pool maintenance
I took about 15 minutes of my time to try to calibrate this thing. The directions are unclear, first off, so it seems to say that it wants you to dissolve all 3 powders it comes with into the same container, but that is not the case. You are to mix the 3 calibration powders into their own individual 250 mL containers of distilled water.I was unable to get my unit to calibrate accurately. I ended up giving up on getting the calibration accurate when the unit would reach 6.81 in the calibration liquid which was supposed to read 6.86, so no, this is not accurate down to .01 ph. Still, accurate enough to do pool maintenance so I give it 3 stars.

Make sure your plants have the right ph level!
Item works perfect! Would recommend!

Inconsistent results!
I followed the supplied directions and soaked the meter in distilled water before every use and this process is a little cumbersome. Even though I was doing this before each use, I still got every time different results which fluctuated from 6 to 7.9.That’s a lot! I even compared it with test strips as well as a liquid test kit and it only matched up one out of 5 times. I am not able to recommend this PH meter.

Doâs & Do not doâs; Get the full education of pH Pens before buying
There is seriously lacking written material or a write up accessible by a QR code or website for operation. If your seeking a pH Pen for accuracy, make sure you at the very least know this:Store at all times upright! Your best bet is a pH 4 or 7 buffer solution; letâs say a KCl solution isn’t available, you can use a pH 4 or 7 buffer solution as an alternative.Never store in distilled or deionized water: These waters lack ions, which can leach ions out of the pH electrode’s glass bulb and damage it. Donât purchase something you need precise measurements from and not keep it in top shape.In a situation where you use it regularly, store it in the protective cap; fill up the protective cap provided with your pH pen to halfway with the appropriate solution and place the cap on the electrode, ensuring a snug fit- upright so the bulb & electrode tip stay moist.Ya have to regularly check and replenish the solution. Set a phone alert, write it on your whiteboard, calendar.. whatever. Just make sure you are doing it regularly. If the solution level drops, replenish it to keep the electrode submerged.If it does dry out you can recondition a dried-out electrode by soaking it in pH 7 solution. How long? It needs a good enough soak for at least an hour (preferably overnight) before calibrating and taking measurements. This pen should have a life of about 10-18 months before its time to replace.

Works well
I got this ph tester to test the well water on my remote property. New distilled water should have a ph of 7.0. However, distilled water will absorb CO2 from the air which creates carbonic acid and lowers the ph. The more CO2 it absorbs the lower the ph. I tried this on a new jug of distilled water and got a reading of 6.92. The tester comes with 3 packets of chemicals which will make 3 different ph solutions for calibrating the tester. I have not done this as I don’t need the ultra high accuracy that this meter is capable of. Much easier to use than the strips that I was buying from the pools store.

easy to use
This is so much easier than PH test strips! Less mess and no more test strips to buy – a money saver! It is easy to read and the response time is within 30 seconds. The photos show the difference between our tap and filtered water.I wish the company would have enclosed the PH chart that appears on their product description page.
