Can this work for any digita ph meters? or just one specific one? Thanks!

Any. All ph meter should be calibrated once a while with a solution like this. You will find helpful to use the one suits best for your measures. Lets say you have to measure ph levels arround 5. So you get the 5 calibratiom solution. Or you need to measure arround 11, then you get the 11 calibration solution. Or like me, for marine aquarium, that o need to be as acurate around 8, then I use this product. Some meters will require two calibration Solutions, check that too.

Probably work, but to be safe, you will need to add an external component: ether a LM7812 regulator, or a 6 volt to 12 volt zener in series with the power lead. But even if operated from a safe voltage, the manufacturer has an operating defect with all these units: The digitization resolution is only for two digits. The third digit is useless. The unit "jumps" or steps in about 1.8 degree increments.

As far as I know you don't. I have two other oxymeters and have taken overnight tests with professional grade recorders and my meter reads accurate out of the box when cross-referenced with the other meters. It is important, at least for me, to remember I can vary up to 5 points depending on what finger I use with any meter. Anyway, my meter came accurate and didn't need calibrating so I never looked in to it.

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 ..

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

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 max output of a usb will widely vary depending on what you attach to it. If you are using this to just measure output from a non-usb thing, this meter may not work at all. For example, if I use a special charging cable that is not a data cable, this meter does not work.

I would think that depends on the moisture level (humidity). It would certainly work but if the gauge itself is in the same high humidity environment as the probe, it might not have as long a life. I use mine at ambient room conditions with the probe in a lab oven at 113F and 70% humidity. Works great but my gauge display is always cool and dry.

I purchased this product specifically for testing the pH of water. It's actually a test for the pH of water for plants. I wasn't able to find another good product for specifically testing the pH of drinking water, so I got this one and it worked well for me. However, it isn't for testing urine. There are many products out there (usually strips) that are made specifically for testing the pH of urine. You can find pH strips for analyzing urine right here on Amazon and you can see from other user's feedback if they are good or bad. If you are still interested in possibly using this product I would go directly to the company and ask them your question since it's their product.

Yes. The same API for the BP monitor works for the other Withings devices as well.

Yes I suggest you try a side by side test to make sure. You can contact their website with questions. I believe they make a meter also.

A standard litmus kit cannot accurately test the pH of water due to the chemical traces on the strip and the reaction process..... Seriously? Those chemical traces and the reaction process are EXACTLY how pH is determined. This is like saying a speedometer can not be used to measure speed because it measures distance traveled over time...... /smh

I used it for a replacement speed dial on a mobility scooter which is not what it was designed for but I believe the measurement for the scooter is in linear units because the potentiometer worked. Hope this helped you.

This meter DOES NOT MEASURE pH....!!! The meter case is plastic and waterproof but it does not have a separate plastic case or box.. It is a great meter for what it was designed to do..

You can try it, worse case just send it back, but I don't think it will work. Maybe you could see if you can mount it on your meter. It's a very helpful tool.

They work, but your meter must now have a "permanent" key code inserted in it. Key codes are no longer supplied with test strips. You can get one online at https://www.accu-chek.com/microsites/black-code-key/request.html

you can use any code chip that comes in the strip box. just put it in the meter and turn it on to see if the code displays same as on the chip.
