Hanna Instruments HI3834 Iron Test Kit for 50 Tests

The Hanna test kit determines the iron concentration in water by conversion of the ferrous (Fe2+) state. The test is fast, easy and safe. The color cube makes it simple to obtain the iron level in water. Iron can exist as ferrous (Fe2+) or ferric (Fe3+) ions. The Hanna test kit determines total iron levels in water via a colorimetric method. First all ferric ions are reduced by sodium sulfite to ferrous ions. Phenanthroline complexes with ferrous ion to form an orange colored solution. The color intensity of the solution determines the iron concentration. Test kit comes with 50 packets iron reagent, color comparison cube and 20mL plastic vessel. Colorimetric method. Range: 0-5 micrograms per litre. Smallest increment: 1 micrograms per litre. Phenanthroline chemical method. For 50 Tests. Weight: 142.5gm.
