Potassium Reagents (300 tests) - HI93750-03

The HI93750-03 are reagents for the colorimetric determination of potassium. There are enough reagents for 300 tests to be used with a compatible benchtop or portable photometer. 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 and packet for traceability.

  • Pre-dosed reagents for ease of use
  • Supplied with certificate of quality
  • Marked with expiration date and lot number for traceability


The HI93750-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the Tetraphenylborate method. The reaction between potassium and reagents causes turbidity in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible benchtop or portable meter can be used to determine the concentration. The results will be displayed in mg/L (ppm) of potassium. Based on the range selected with the meter these reagents are designed to be used with samples that have an expected concentration between 0.0 and 200 mg/L potassium for benchtop photometers and 0.0 and 100 mg/L potassium for the portable photometer. Each meter offers multiple ranges.
