I got a refund no problem, just follow the directions.
Glenn Matthews
I really like having this digital PH meter instead of using liquid test kits to check the ph in my saltwater tanks.
Luv2play01
I finally had the time to try it out, unfortunately the reading won't stabilize in anything.

Size Name: PH-2011 Verified Purchase
I got this pH meter as a cheap means of measuring the pH during my brewing process. Later it might also be used for analyzing our pool but first this endless winter has to stop...

When I received the pH meter I tested its accuracy in the lab against our standard buffers. Initially it was way off but that was most likely because it was freezing outside and the pH meter must have been thoroughly chilled on the delivery truck. I let it warm up to room temp for a few hours and tested it again. So here are my observations with the pH meter being at room temperature:

The readings took a long time to stabilize (a couple of minutes maybe) which might or might not be a problem for the user. If you want to do titrations it's probably bad but if you just want to check the pH at any given time it's working fine. One observation, however, worried me. Whenever I got close to the device the pH value changed drastically, sometimes up to 0.5 points! This must have been caused by electrostatics of my clothes or gloves that I was wearing.

The pH meter needed a little tweaking to display the correct pH values according to the standard buffers. I tested 4.01, 7.00, and 10.01 and every time the measured pH was within 0.02 points, so well within the given specs! You will need to gently shake the pH meter after placing it in the solution you're trying to measure to ensure you don't have air bubbles stuck to the electrode.

I also managed to use the pH meter during one of my brew days and it was interesting for sure. Hopefully this will not only be a gadget for "informational purposes only" but also help me improve my beers by mashing at the correct pH.

Bottoms up!

Size Name: PH-2011
My wife purchased this product, but I am using it as well. Model: pH-2011.

MY OVERALL IMPRESSION is that it is a quality device that will last for some time (we have had it briefly). Calibration is accomplished with distilled water (no tap water) and the included goodies. NOTE: instructions are in Centigrade (Celsius). Comes with storage container which is semi-translucent plastic throughout. In operation the display is illuminated green, and shows momentary continuous readings. No time-out feature has been noted/observed. Make sure to turn it off when done to maximize battery life. Included cover for submersible "business" end of device and pen-style pocket clip (plastic) for mobility. Adjustment tool / mini-screwdriver included. Meter, tool, and instructions all fit in the provided case for storage - nice.

IMPORTANT: do not submerge device beyond the portion where the cap fits as it is not 100% waterproof. Use of centrifugal force to remove excess water after a reading is recommended for longevity of product.

USES: fish tank water maintenance, liquid fish food solutions, liquid plant food/fertilizer solutions, tap water testing, liquid testing of any kind.

CALIBRATION: Included in the packaging is only enough for initial calibration. The device will need to be calibrated again. How often depends on your need for accuracy of readings and duration of, and between, uses as it relates to battery life. The interwebs will give you homemade test solution recipes. If precision is desired you must purchase CALIBRATION / STANDARD REFERENCE SOLUTION which is usually 7.0 pH at 77 *F (25 *C).

THE FUGLY: This was purchased with the intent of testing the pH of... soil.

Size Name: PH-2011
I was skeptical when I saw this product online, as I am un-happy with the performance of a Hach Sense-ion ph meter. But, this unit is a fifth of the cost of just the Hachs probe, which I replace twice a year.
Calibrating this unit is a breeze. The directions are clear and easy to follow. I like the clip on the side, I use a magnetic stirrer and clip the meter on my beaker and wait for it to stabilize. I checked this unit against my Hach sense-ion and the Etekcity Ph Meter was either .01 off or dead on the hach. I tested raw well water, treated potable water, PH calibrating liquids of 4, 7, and 10, sewer influent, effluent, and mixed liquor. Etek's performed flawlessly. I will never spend hundreds of dollars on a PH meter again, not to mention the $200 on probes every year.

There is a night and day difference between the top tester by Etekcity and the cheapest. The first one I got was the ph-009IA that was broken out of the package. Damn near killed my plants directly after calibrating. I replaced it with the 0.05 with ATC. Much better. I like the backlight screen. It seems to be more stable and the glass covering the electrode hasn't broke yet.

High Accuracy my butt.
I purchased this to (hopefully) monitor the pH daily in my newly constructed pool.
I followed the calibration instructions but never got repeatable readings.
I was skeptical that any pH probe could be so inexpensive and this was the case for me.

I'm an Electrical Engineer and have worked in Water/Wastewater for years so I know quite a bit about analytical instrumentation. Typically and instrument has a "span" and "zero" adjustment. This has only one potentiometer to adjust so it can really only be accurate for one reading. I even purchased additional pH 4,7,10 solutions to try to make it at least usable before I finally gave up. I switched to the Lamotte ColorQ-7 and have to say I'm extremely pleased with the accuracy and repeatability of this test (it was 10x the price.)
