Details

pH 4.5-10 triple pad test strips are good for enhanced pH verification. Use them for saliva, urine and science fair demonstrations where resolution is needed for a narrow range than the 1-14 range. This can be very handy when testing different foods and drinks which occur mostly in this range.

The 3 test pads give 0.5 pH resolution and with practice, one can estimate 0.25 pH intervals. See some of the examples below.

The pads on an unused strip are calibrated at ~pH 5.75. Changes can be subtle & appear different under fluorescent, incandescent or sunlight. So, experiments done in the kitchen might appear a bit different when repeated in a school gymnasium.

Excellent product. The strips are packaged well and easy to use. The triple pads make it quite easy to read very accurately. The order was very well packaged and delivered quickly.

I have been using Indigo Instruments test strips around 10 years now. Before I found them I think I have tested maybe 15-20 different test equipment and have found that Indigo test strips are way superior to any and all the other test strips I have tried. Usually fast delivery I am in California and I have them 3-4 days in the mailbox.

Better sensitivity (0.5 units) than typical pH paper. Provides accurate results without the need for electronic pH tools in difficult environments for electronics. And NO calibration needed.

I discovered this company accidentally many years ago when I was seriously ill with no diagnosis. I used the pH strips to double check the medicinal test strips I had bought in order to diagnose myself. At first I bought only a bag of test strips; now they all come in a plastic box. The quality is very good; the tests are reliable; the strips last for over a year. The company ships immediately, and the product arrives to Norway in just a few days. I once sent an enquiry about the pH in drinking water (low due to acid rain), and I had an email discussion with a professional who works with the company. All in all, I consider Indigo a serious and professional website, and the pH tests of high quality.
