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.

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.
