PH20 Value pH Tester

Excellent, thank you. It reads quickly and accurately. Great little container it comes in too. Very fast postage from Amazon. Cheers.

More accurate than my test drops at least, seems well built and designed. Case and detailed instructions and laminated sheet with quick instructions/care is great. Batteries don't die quick another plus. Compared to the other reliable PH meters fair priced. Do not go cheap and get the yellow ones unless you are going to double check it with test drops( even then I don't trust them to be .5 ph accurate)

Great option for the price! Very compact and easy to use. I've used it to make skincare at home and so far it has been reliable and easy to clean.The only thing to consider is that the cap is not so well sealed. I filled with a storing solution but it leaked a little.

I bought this tester mainly to verify two cheaper ones I had already. I was just not confident the ones I was using were giving me accurate readings. When I tested them with calibration solution they both read slightly off one being higher and one lower. So I decided to spend the money on a higher end model.The Apera model seems to work very well and when tested in calibration solution is usually spot on. It has a nice LCD display which is easy to read during normal operation and is much quicker at determining the PH level versus the cheaper ones where you need to wait a while for them to stabilize and typically have much smaller and darker displays. That is the good news, however, the calibration procedure is a bit clunky compared to even the other cheaper ones I have. Partly due to the instructions which are very poorly written, hard to follow and provide contradictory information when it comes to things like storing the device. I understand it was made in China but for gosh sake, hire someone who knows how to speak and write in English to design the manual so it makes sense.In my application PH is very important so having more than one tester is not a bad thing. But it I had to pick just one and price was not an issue....then yes, I would chose the Apera model, but by a very small margin. Mainly because it appears to be a higher quality, well made device - even though the included instructions and funky calibration procedure hold it back from a five star rating.But in the end it is only slightly more accurate then the $10-$15 ones I already have. If the accuracy of the PH reading is that important to you and you want the best and do not care about spending $50, then the Apera is a fine choice. But if you are on a budget and are using a tester to check the PH of say swimming pool water, a cheaper model will work just fine. I would recommend getting two cheaper units from different manufacturers so you can check them against one another. You will spend about half of what it cost for the Apera. And as long as you occasionally test and re-calibrate them, you are better off with two cheaper models than the one more expensive one that does the same thing.

This right here is a key piece of equipment when growing anything, I bought the apera based on the review of 420scene on YouTube. I've had this for 3 months now, it does not loose calibration like my other meters. I do however calibrate once a month to be sure, and it's always on point! Just nice to to have piece of mind. I bought the regular kit, and ordered the storage solution separately, looking back I wish I got the big kit with stand and cleaning brush and extra fluids. The regular kit still comes with everything you need to get started. If your on the fence, just do it! It's better than spending a lot on the big blue brand and I'm glad I didn't and got this! Batter life is awesome, the casing is sealed and prevents water and nutrient solution from entering. It does have an auto shut off after 5 minutes, the overall quality it nice, it's git decent weight for handling, the screen is easily readable, only thing I would change is the LCD being lit up, there is not backighting.

Over 2 years in use. It has been through it all, its missing pieces off it, its sank to the bottom of the reservoir, its filled with water under the cover and screen, its sat outside. It still works at 100% accuracy. Best pH pen ive had, its like the nokia of pH pens. Used multiple times a day.
