Good for the price By John from Dallas on 3/16/2016John from Dallas would recommend this product to a friendI'm sure they're better ones out there, but not for the money. Mine stayed accurate for 9 months! However, I bought a second one after giving my first one away and it came needing serious calibration. Make sure to buy calibration fluid.
Garbage By Timmy on 11/11/2014Timmy wouldn't recommend this product to a friendDon't buy it. I checked this pen after 1 week and recalibrated in 7.0 as well as tested in 4.0 ... It checked out. But the when I tested plain tap water and compared the results to my fail safe drops (never been wrong) it was a whole 3 ph off! If you are going to only spend $20 might as well save a few cents and stick with the drops. Pen wise just spend the money and get a legit one. PENS SHOULD NOT HAVE TO BE RECALIBRATED BEFORE EACH USE! Now I've got to fix heavy nutrient issues in all of my "house plants".
Very Unstable -cannot make any sense of a reading By Lee on 10/30/2014Lee wouldn't recommend this product to a friendReceived this probe and was hoping it wasn't the same one that a company that I was a bench chemist for bought back in 1996. But it was. It is a POS. The reading jumps around indiscriminately, it will even give reading that make no sense like 20 or 30. Sometimes the decimal is there and other times not (like 50 or 5.0). I would say I got a bad probe, but as far as I can remember it was the same as we had received back in our lab 18 years ago. Feel free to press you luck!
Works well for me, stays in calibration thus far. By Mike on 8/26/2014Mike would recommend this product to a friendMine also came coated with a solution that had dried up as well on the probe under the cap. Probably from the manufacturer. Simple rinse and its gone, calibrated it with 7.01 fluid and tested it with 10.01, was dead on. Bought extra solutions to check it from time to time and after 1 month of use has stayed in calibration, very happy with. I rise in freshwater after every use and give a good shake before putting cap back on, its NOT necessary to store in calibration solution contrary to the directions, hence the cap. :)
Came covered in salt By Dmitry on 1/19/2014Dmitry wouldn't recommend this product to a friendNot sure why, but the unit came without any liquid inside (I thought you had to use it to store the probe) but instead it was covered in salt, as if it was already used.
Dont buy it By INXS on 11/7/2013INXS wouldn't recommend this product to a friendThe meter appears to be accurate as long as you calibrate it before every use. However beware of the 30 day warranty...My tester has already quit working and I have only had it for 4 months !
Great By Keith on 7/30/2013Keith would recommend this product to a friendWay better than going blind trying read those color charts.
Don't forget the Calibration solution!!!!! By Lukee on 1/9/2013Lukee would recommend this product to a friendI just ordered this product and then found out I need calibration solution!!!!! Don't forget so you don't have to pay for shipping on a $0.99 product!
quick and accurate pH By Paul on 1/2/2013Paul would recommend this product to a friendVery nice handheld pH meter, compact yet easily read LCD display. Seems to remain quite accurate for me even though I store it dry, with cap on. Used for 4-5 months without calibration, tested it with ph 7 & 10 reference solutions, was only off by .1 with the ph 10 solution.
a must By Brian on 6/11/2012Brian would recommend this product to a friendbuy this instead of trying to read color charts on a test kit. be sure to buy some of the 7.0 calbration packs
great instrument for the price By Michael on 4/28/2012Michael would recommend this product to a friendexactly what I've been looking for. easy to calibrate, easy to use, and the price was right for my budget.
Accurate, but, loses calibration frequently By Kirk on 3/11/2012Kirk wouldn't recommend this product to a friendThis pH pen is great for the price, but, it loses its calibration, by as much as 0.8, in just a single day of not using it. I store the probe wet as per the instructions, and when going to check the pH from one day to the next, the unit has lost its calibration. It is almost an entire pH unit off when comparing it to my tanks' pH monitor/controllers (both with new, calibrated probes from the same order as this item was from). Every calibration solution costs you a buck, so, with the need for such frequent calibration, it costs more to use this than a test kit, even though initially, the cost would have been the same as that of a good quality test kit. The calibration screw is a pain to get to as well, as it is on the back of the unit while you are trying to read the front of the unit to set it, and, the screw is not centered in the middle of the recessed hole, so you are forced to put the screwdriver in at an angle to get to it.
