Hanna Instruments HI-739-26 Fluoride HR Reagents for HI-739 Checker

Sale price£45.26

The HI-739-26 are the replacement reagents for the HI-739 Fluoride High Range Checker® HC. 

These reagents follow the SPADNS Method in which the reaction between fluoride and the reagent causes a colourless complex in the sample.

By simply adding 2 mL of SPADNS reagent to two cuvettes, and subsequently 8 mL of the second reagent to one and 8 mL of sample in the other, the reaction will take place and the HI-739 will determine the concentration from the colour that is produced.

The results will be displayed in ppm of fluoride. These reagents are designed to be used with samples that have an expected range of 0.0 to 20.0 ppm (mg/L)
