The MI528-25 Iron Powder Reagent Kit contains high quality reagents ready for use with the MW14 (Art. No. 895550). The MW14 meter and reagents use the USEPA method Phenatroline 315B adaptation. The reaction between iron and the reagent causes the sample to turn orange. Simply add the reagent to the sample, wait for the reaction and the photometer will determine the concentration by the colour. The reagents are designed for use with samples that have an expected range of 0.00 to 5.00 ppm (mg/L).- Reagent kit for iron powder (25 tests)- Pre-prepared reagents for precision and ease of use- Labeled with expiry date and lot number for traceability- For use with the MW14 tester
