Hanna Instruments HI3845 MR & HR Chromium test kit.

$80.03

Hanna Instruments MR and HR chromium test kit. Chromium salts are widely used in industrial processes, in galvanic plants, in tanneries and chemical manufacturing plants. Chromium can therefore be found in industrial discharges and must be monitored because of its toxic nature.

The HANNA chromium test kit is field portable and can also be used in the laboratory. HI3845 is able to determine traces of chromium up to 1000 ppm.

Chromate is determined by a titrimetric method. Only the hexavalent chromium will react with iodide in acid solution. (Step 1:) The amount of iodine generated is equivalent to the chromium in the sample. (Step 2:) The liberated iodine is then titrated with standard sodium thiosulfate solution that reduces the iodine back to iodide ions.

HI 3845 test kit comes with chromium MR-HR reagent A (100 packets), 17 g chromium MR-HR reagent B, 60 mL chromium MR-HR reagent C, 25 mL starch indicator, 20 mL calibrated vessel, 1 mL plastic pipette, graduated plastic test tube with cap. Ranges 0-100 mg/L (5 mg/L) 100-1000 mg/L (50 mg/L). Iodometric method. Approx 100 tests.
