How accurate is the testing? I need to know if my water is 7.0 or 7.2 or 7.5, etc. Thanks

Hi. I have nothing to compare them to but this is exactly why I purchased them. They seem accurate. Good luck!

Use what you got :), I would start by having it hooked up and take readings with my VOM to compare all hookups to verify accuracy of all readings.

The one I received was pretty close about 0.2 if I remember correctly. It is not really an issue though as it comes with chemicals to mix calibration solutions. You just need to mix it with distilled water.

I no longer use my Zero Water tester, but it seemed to work when I used it. I did not compare it to any other tester. I buy Culligan water now, therefore I don't have to test my water anymore.

Did you calibrate with distilled water like it recommended? If so and it's still off I'd send it back for replacement or refund. All the chineese knock offs have tendencies towards really good or occasionally defective. There not put through riguous testing before their shipped. Mine worked great.

I use this for measuring my OG and FG of my beers. My friend who got me into brewing and works for a national beer supply distributor also uses this. You can calibrate this with distilled water. Does that mean it's accurate? I have to think so. I have not compared the results of this against my hydrometer, but if they were off I'm not sure which would be more accurate.

I have never calibrated mine and not sure how you would do it short of sending it back to factory. I have compared mine with several other test sets and also the system at my pool store and found it to be very accurate.

I'm running 4.433 on stock right now. Temps can get warm but not detrimental if you turn up the cpu fan speed. Completely stable as well.

There are specific water flow requirements for these units. Check to see that your system meets these Also check screen filter to be sure it is clear.

They were trying to say 7.4 - 22.4. Don't forget to calibrate this properly! It scares you when you don't haha

Mine is 24.84. According to their site they have switched to 25.5 so there is a disparagement in mine and what their official site claims. I read somewhere else they switched at some point so I may have an older model.

Mine is 18.2, 21.5, 14.8. Not quite sure why the comparison chart is different than the specs. I am happy with it though.

I would recommend getting an inexpensive alkaline testing kit and test the water from the PUR. If it tests sufficiently alkaline, then no. If it tests closer to neutral, I recommend the H2gO product. I use and enjoy mine very much.

If you are referring to the calibration solution, I just used ro/di water and made sure it wasn't registering any salinity.

Out of curiousity, I waited and changed mine when the water started tasting funny. Of a family of 3 1/2, about two months! So, the product description is fairly accurate.

2.2 GPM with both on. with one on I would speculate it is more than 1.1 as it increases the water output of the single device. I would guess maybe between 1.4 and 1.7 with just 1 on.

I have my bottle for a couple of years now.. I use it sporadically and it always is consistent with the 7.0 reading..
