pH Test Kit Replacement Reagents (300 Tests) - HI38058-100

The HI38058-100 are replacement reagents for the colorimetric determination of pH with the HI38058 pH Test Kit. There are enough reagents for 300 tests to be used with Hanna’s test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each bottle for traceability

  • Pre-made reagents for ease of use
  • Prepared with high-purity chemicals
  • Marked with expiration date and lot number for traceability


The HI38058-100 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate pH measurements with the HI38058 chemical test kit. These reagents follow the colorimetric method to determine pH.

For determination of pH, HI 38058-0 reagent reacts in contact with the aqueous solution changing its color according to the hydrogen-ion concentration (pH) in the given range. The reaction causes a colored complex to form; the greater the concentration, the deeper the color. The Checker Disc supplied with the kit allows for an accurate, side-by-side, visual analysis to determine pH concentration. These reagents are designed to be used with samples that have an expected pH range of 4.0 to 10.
