Has anyone established the accuracy of the product by comparing to other testing devices?

One could worry about the exact accuracy of this device, where I feel it is more a relative reading, and tells you the approximate amount of solids remaining in the water. For the most part, after filtering the water, the ZeroWater device reads zero.

I think it is more accurate than the light one that come with the 8 cup pitcher. When this tester reads 009, the included light only tester stays dark.

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.

I have not compared the accuracy of this product. However, just today I tested my filtered water and then decided to test the water as it came from the spigot. The water from the spigot showed over a 2.0 reading. I check my filtered water periodically. If the reading is near or above 0.6, I then change the filter on my pitcher. I've been very pleased.

Yes but this product wasn't worth the money it was not accurate at all. Hope this helps

Mine is not accurate, but I've always used a Maverick digital anyway, so I was never concerned about it.

Yes it has been tested. Feel free to contact us and we will be happy to provide you with the report.

I used a cigar hygrometer calibration kit to test it. Inexpensive and accurate way to test the probe for accuracy.

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.

I'm not sure about specifics on their testing procedures, but I can say I have not encountered any supplement companies as good as them. The products I have used are all good and they even send free samples of their products. Might be a question to ask their customer service.

Yes, from what I have experianced the manufactures claim of accuracy of .02 is correct.

I have found the machine is accurate but sometimes blood pressure fluctuates.I have another machine I test this unit in question.

My answer would be a big YES... it seems very accurate and I often compare it to the one my Step-mom uses daily at her Hospital job.It's consistant within 2 or 3 percent. My husband and I are in our late 50's and we both use it once every morning...again after our daily workout at the Gym...and again a few hours after the Gym workouts. six times a day and it has never failed to give good solid readings.

Accuracy I'm not sure of. It appears to be very stable no crazy spikes. I like it better than the GSC10.

Yes it does. I've had good luck with how easy it is to use and how accurate. It's a good product.

I have used it (the 780) for 2 1/2 months. I did get an ERR message twice but the device started the process again on its own initiative in the three pressure average mode. I checked this one for accuracy against a very old Omron, about 25 years, that had been checked against the one in the primary care's office. It has been consistent for the time I have used it.

Just got mine a year ago. It is very accurate within it's stated variables. I have two friends with iphones- they are all over the area while my eTrex 20 usually takes me very close, if not right to, the cache. Two thumbs up!!

I don't understand the question, but regarding accuracy of readings, I have no other calibrated instrument with which to check the accuracy of the readings displayed with this product. Generally, they appear to be reasonable based on published noise decibel readings.

I have no other device to compare it with so I have no idea of it's accuracy. We use it for comparitive purposes so for that it's useful. The "manual" is very tiny page, with a tiny chart for weighting and frankly I've misplaced it. Other than that, there is little info. However it does seem very well made. I has the feel of a Fluke multimeter.

We used it to test for lead and we have no reason to believe the result was inaccurate. All of its other tests gave results that made me feel like the test was genuine.
