Hanna Instruments HI3846 Chromium VI Chemical Test Kit uses the diphenylcarbohydrazide method to measure hexavalent chromium.
The HI3846 determines the chromium concentration in samples within a 0.0 to 1.0 mg/L (ppm) range. This kit comes with enough reagent for approximately 100 tests.
Readings from 0.0 to 1.0 mg/L CR+6 are determined with a smallest increment of 0.2 mg/L.
