High quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the Ferrous Sulphate method in which the reaction between nitrite and the reagent causes a colour change in the sample. The intensity of colour is determined by a compatible photometer and the concentration will be displayed in mg/L (ppm) of nitrite. These reagents are designed to be used with samples that have an expected range of 0 to 150mg/L nitrite.

• Suitable for use with the HI-96708 & HI-97708 portable photometers and the HI-83200-02, HI-83300 and HI-83099-02 multiparameter bench photometer
• Reagents for the colorimetric determination of nitrite
• Enough reagents for 100 tests
• Clearly marked with the lot number and expiry date on each packet for traceability
