Dont buy it By INXS on 11/7/13

The 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 !

I 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 1/2/13

Very 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 6/11/12

buy 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 4/28/12

exactly 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 3/11/12
Kirk wouldn't recommend this product to a friend
This 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.
just a great little meter By Robert on 2/22/12

I didn't buy mine (I"ve had 2 so far) at BRS, but I thought I'd throw in my .02 in case anyone is wondering if a $20 ph meter can be worth a crap.
It totally rocks. I'm utterly baffled at how it keeps so close to calibration -- sometimes for months and months in storage.
Another poster mentioned 'how do you keep the tip moist'? A: the cap is /supposed/ to be water tight. My experience is 50/50 at this point. The first one I owned was tight as drum. All I did was take a little square of sponge, moisten it w/ tap water (use 7.0 calibration sol. or storage solution if you have 'em) jam it into the cap and then put the top back on. Should keep quite a while that way. Don't forget to turn off the display!!
The second meter I have, has a looser cap and I find I have to tape it shut and keep it sealed in a baggie to ensure that the tip keeps moist. Bummer but I don't use it that often. I really just keep it around for emergencies and sanity checks. Well worth a twenty, it's come in handy lots of times.
Good for a quick reference By Miguel on 2/21/12

This ph meter is excellent for a quick refence of how your tank is doing but needs to be calibrated before.
well made! By Alan on 2/21/12

.1 accuracy. 1 point calibration. Not the most accurate; but, I double checked it against a pinpoint and it was okay.
Not sure about this. By Stephen on 12/28/11
Stephen would recommend this product to a friend
Seems like a good product, but the instructions say to keep the probe wet? Don't know how I'm supposed to do that when it says not to store it in RO water. I haven't kept it wet, but it seems to be working well.
