Covalently bound pH strip indicators won't bleed or dilute.
Test 0-14 pH range with a single measurement or try one of your narrow range pH strips that will pinpoint the pH you're trying to measure.
Perform pH tests in seconds for just pennies a test.
Get accurate measurements in weakly buffered, turbid and even colored samples.
Carry pH strips in your pocket for use in the lab or field colorpHast pH strips give you confidence in your results.
With colorpHast pH strips, you can test the pH of trace samples without worrying about contamination.
You can even test weakly buffered, colored or turbid samples and still get accurate results.
For samples such as mud and sludge, all you have to do is dip the pH strip, rinse and read the result.
