Great ! Even brought a spare as they work so well. Very accurate and easy to use. No need to spend a fortune, perfect at this price.

Works quickly measuring PH within seconds. Solid read out. Had it tested and it is completely accurate. Pleasant surprise at this low a price point.

I’ve not been this frustrated for a hot minute. I just spent the better part of two hours going back and forth calibrating and re calibrating this stupid pen trying to stabilize the readout and it just won’t work. It reads properly for the test liquids at first and then when I go to actually use it for something I NEED it for and what prompted the purchase to begin with- it DOES NOT WORK. The readouts are off by over 2 whole points nearly every time. Even just testing it to see if it was a fluke, I tried reading my distilled water and it’s telling me it’s at 4.9-5.8 when I know dang well it sits at a perfect 7.1 every time. This pen is utter garbage - unless I got a bad one? I dunno. This has been SO frustrating!

I was pleasantly surprised by how easy it was to set up and use. It was a little annoying getting all the powder to dissolve for the 4.0/7.0/10.0 solution tests, but easy to calibrate after that, and has been working great ever since.The display light turns off a little more quickly than I'd like, but that's a minor inconvenience at best. I appreciate that it gives me pH and temperature.

I needed a quick replacement when my other ph pen died. This pen filled the roll incredibly well. The included temperature gauge is an amazing value and seems relatively accurate. I have not tested the temperature against another meter.The other brilliant feature is the backlight display that auto shuts off after about 10 seconds. you can still see the reading, but the backlight turns off to save battery.accuracy - this pen, When tested against my Milwaukee ph pen shows a difference of only .1, this is without calibrating the YINMIK ph meter out of the box.reliability - used for only about a month so far without issue, will update if it fails. accidentally fully immersed the meter in water for 2-3 seconds. dried the exterior and it remains fully functional.support your local brands when you can, but this is a GREAT backup pen.

I first tried PH strips, after getting no change from them, I bought this meter. I used it right out of the box. It seems to be pretty close to accurate without calibrating it. since I'm interested in approximate figures, I felt that it was fine. It does come with packets of calibrating powder which I'll get around to using at some point. The goal is to use this meter to measure urine acidity and through the use of baking powder tablets raise the PH to between 6 an 6.5. This will dissolve uric acid stones and prevent new ones from forming. So any approximate number around 6.3 is what I'm shooting for. This meter should do the trick. The cost is in the same ballpark as the cost of strips so this seems a better buy even if I did find a strip to work.

Reevaluated after 1 year….This PH meter comes with calibration packets and instructions. I used it out of the box and checked accuracy with our pool supply vendor and the numbers were accurate. I did not need to calibrate but a year later I found this impossible to calibrate to 7.0PH so not the best option over time. I was having a difficult time reading the test strips for my small above ground jacuzzi so I purchased this meter. It has helped me to keep the water PH levels where they need to be until I lost confidence and started a calibration. I also noticed some mold forming around the sensor after following directions to keep the sensor storage cap moist. It is a great value but it started to give inaccurate readings after a year of use and calibration did not work as instructions show. I do not need the temperature function but this works well.
