Hanna Nitrite Low Range Checker Reagent 25 Tests (HI-707-25)

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

The HI707-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Nitrite Low Range Checker HC. These reagents follow the Diazotization Method in which the reaction between nitrite and reagent causes a pink tint in the sample. By simply adding the packet of HI707-25 reagent to the sample, the reaction will take place and the HI707 will determine the concentration from the colour that is produced. The results will be displayed in ppb of nitrite. These reagents are designed to be used with samples that have an expected range of 0 to 600 ppb nitrite.
