Does anyone know how reliable the PH level is? I am looking for 9 +. Thank you.

We tested it at the beginning of use and it was an 8. I haven't tested it since. By the way, my friend uses prill beads in a beverage dispenser (those big glass ones with the little faucet) and had the same rating of 8.

Interesting question. I didn't know, but I suspected a slight increase. I tested tap and filtered water this evening with my color comparison pool test kit. Results in my area are, from the tap, 7.5 Ph, from the filter 8.2 Ph. When my pool gets that high, I add acid to bring the Ph down, it's better for keeping the calcium in suspension (we have hard water in Riverside, Ca). To be honest, I didn't expect this large of change in Ph. Thanks for pointing that out.

I have well water that is about 7-9, seems like ph stays about the same, it might drop a point. This machine is awesome man it takes my 485 ppm water down to about 12

Yes and no. You can get it close with only 7.0 but for more accurate reading you need 4.0 and 10.0 or ph test strips (paper test strips)

Hi ...I have just done a short search. It appears to me that the 14 is for residual testing. I am not clear on residual Ph. I think I would stay with the reagent 4. Hope that helps!

pH on this meter is 0-8. no calibration needed, just cleaning with pad before use.

Thank you for asking Linda; the pH can be adjusted to a range between 8.5 and 10. Please feel free to call: 970-485-5955 or visit us at WaterForHealthUSA.com Thank you for your interest. Bert Middleton

Margaret, I can't find the PH on the bottle anywhere, and I do not have the pkg anymore. Sorry I couldn't be more help. Thanks, L. Sinner

FROM HM DIGITAL: The PH-200 meter is three-point checked and factory calibrated to pH 7.0. While this is suitable for many applications, It does feature digital auto calibration to pH 4.0, 7.0 and 10.0. The meter should be re-calibrated once per month and it is recommended to re-calibrate it as close as possible to the pH level that will be tested in order to get proper results and prolong the life of your meter.A free packet of pH 7.0 buffer is included with the meter. Additional pH buffers for calibration are available for purchase.

Depends,A year or so maybe.I would test the PH with another testing kit from time to time.

we have been very happy with our pH tester. It needs to be calibrated occasionally but for the most part stays in calibration fairly well. It's easy to recalibrate and easy to use. We are happy with the tester

Hi Mike, pH Dips have been designed to indicate whole number values for pH and you should easily be able to estimate 0.5 or half units as colors on the test strip may fall in between two whole numbers. I hope this helps. Thank you for your purchase.

the calibrated range of the ph.7 and ph4.0 buffers is .5 degrees accrurate...I have used this equipment for years and find it to be great...have not used the 10.1 buffer solution in food processes...but will tell you this equipment is very reliable...

I used it in my pool with is about 8000 gallons and I have it at 94 degrees. It definitely raises the alkalinity and PH. I stopped using it and now everything back to normal. I read some articles and seems to be more for outdoor pools and hot tubs if that is what you have

First, they have test strips on Amazon for less than $3 that have good reviews and they go below 5.5. I have not used them myself but just ordered some. I use soil and not hydroponics so I'm not sure how to get water to Ph 5.5. They have solutions on Amazon that are specifically made to adjust Ph. And believe it or not human urine can be used to reduce Ph. It sounds ridiculous but it actually works. You just have to experiment with mixing amounts to get to 5.5. And have a bunch of test strips ready so you can test as you add.

if you had a way to check calibrations at that range it would work for a while. A more resistant coating is formed above pH 10.5.

Many ingredients.....am very happy w/results...their Ph No. is 1-888-548-0900
