*HI3824-025 Ammonia Test Kit for Fresh Water Replacement Reagents (25 tests)

The HI3824-025 are replacement reagents for the colorimetric determination of ammonia (as NH3-N) with the HI3824 Ammonia Test Kit for Fresh Water. There are enough reagents for approximately 25 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 packet for traceability

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

For determination of ammonia, the Nessler reagent is added to the sample under alkaline conditions to react with ammonia. The reaction between ammonia and the mercury-containing reagent causes a yellow colored complex to form; the greater the concentration, the deeper the color. A color comparator cube is included for an accurate, side-by-side, visual analysis to determine ammonia concentration. These reagents are designed to be used with samples that have an expected ammonia range of 0.0 to 2.5 mg/L (ppm) NH3-N.
