What is the pH range measured with calibrated using pH 7.01 &amp; pH 4.01 buffers? pH 7.01 &amp; 10.1 buffers?

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...

Well, the packet of ph substance says "make up 250 ml" on the one I have. I think that's what I did.... But it's been awhile.

For correct cyanuric acid (stabilizer) reading, the ph and alkalinity will need to be within range.

I don't think so, the PH range on these strips is 6.2 to 8.4. These strips are very good but not for the PH range you're looking for.

FROM HM DIGITAL: The accuracy of the PH-80 is + / - 2%. It is factory calibrated to pH 7.0. The meter can be easily re-calibrated with digital calibration to pH 4.0, 7.0 or 10.0. All pH meters should be calibrated anywhere from before every use to at least once a month. The frequency of calibration depends on usage and application, but you should calibrate at least once per month for proper results and a longer lifespan 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. For more information, please visit www.tdsmeter.com/products/ph80.html

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

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

In order to calibrATE you do need the packets and thew ionized water. Unless you can get a lab to check it against their equipment

Guy has the best answer so far. Use a solution that is closest to the range you expect to be measuring on a daily or regular basis.The factory has calibrated it a 442 ppm.John

I was looking online, and from my understanding, the pH won't be accurate, and the colors on the color cards won't be accurate, so you will not be able to interpret the readings, but the test results should be the same. Here's one forum that I looked at that can give you more detail:http://www.fishlore.com/fishforum/test-kits/41915-use-sw-master-kit-fw.html

Was easy to calibrate and simple to use. I ordered the buffer solution to go with it you don't want the tip to dry out. There is a celebrating solution also but it comes with some. Mine has held its calibration.

Yes I just did with a digital PH meter, tested in a baseline solution of 7.0 PH and the test sample read 9.7 PH ... close enough .. enough said ..

I've measured it as high as a ph of 10, but it depends on the state of the incoming water and how filtered it is before it hits the machine as well as the internal filter.

since I had not done the acidic check, I do not know why it tested at 6.0. You might want to check with the company. Sorry.

Be very careful about changing your PH. Do it in little increments . If it's at 7 just leave it at that

no solution comes with it but amazon has it in 4 7 and 10 the one i got was right on and hasten drifted in 6 weeks just look up ph buffer of calibration solution and a number of them come up hope this helps

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.
