JNW Direct pH Test Strips for Urine and Saliva - 150 Litmus Paper Strips

Exactly as described and pictured. These strips are very easy to use and read/interpret so they are very useful if you are looking to check, test, and validate the ph/acidity of something quickly. The results were apparent very quickly so you don’t have to wait very long to view. The stops are small so just be aware of that.

These pH test strips from JNW Direct are precisely what I needed to start tracking my pH levels at home. They're simple to use—dip in urine or saliva and match the color to the chart on the bottle. The results are clear and accurate, and I appreciate that the strips cover a wide pH range (4.5–9.0).With 150 strips in one pack, this kit will last me months, even with daily use. The included eBook is a nice bonus, too, packed with helpful info on how to stay alkaline and make healthier lifestyle choices. I highly recommend it for anyone trying to monitor their pH levels and stay on top of their wellness goals!

Great product

The color scale could be brighter but they seem accurate. It's not always easy to decide on which hue matches the scale. It reads acidity or alkalinity . It says not for pool or drinking water testing.

I cannot confirm the accuracy via a calibrated electronic pH meter but these test strips are excellent in providing an easy visual pH reading to within 0.25 or greater. The two-test pad method removed the ambiguity associated with trying to judge the color of a single test pad. One note probably true of many test strips is that the accuracy of one of the reagents is low at the extreme end of the scale. At the extremes, you will end up relying on one test pad or the other but at those points -- pH 4.5 or 9.0 -- you would probably want to take other measures anyway.

These pH test strips are easy to use and come with plenty of strips for the price. Results are quick, and the included guide is helpful. However, the color chart can be difficult to read, making it hard to determine an exact pH level. Overall, they’re decent for general testing but not ideal if you need high accuracy.

I got these ph testing strips to help narrow down when my mare was ready to foal. The ph level of her colostrum should start above 7.5-8.5 in the days prior to labor, then drop to sub 7-6.5 within about 12 hours of foaling. This has given me a lot of peace of mind, knowing I don't have to start worrying too much (and sleeping in the barn for days) unnecessarily! I have found these test strips reasonably accurate and consistent. Yes, they DO come with color already visible on the strips, they just change color after you put your test material on the two reaction boxes on the strip. I've seen reviews complaining that they arrived already colored. It's fine. The color will change! They aren't supposed to arrive with the test boxes invisible. No problems with these strips and no complaints!

Quick and easy test strip for saliva and urine. Helps keep your pH in check.
