ffem - Android App Based Total Iron Test Kit
The ffem Total Iron test kit is designed to provide a rapid and efficient means of measuring iron concentrations in water samples. Utilizing a colorimetric test that involves two liquid reagents, the kit induces a color change in the sample, enabling users to determine the iron concentration. This can be precisely measured using the ffem match Android app, which requires an initial calibration of the Android device. Calibration standards necessary for this process are included in the kit. Alternatively, users can reference a color card included in the kit for semi-quantitative results. Shipping of the chemical reagents is handled by road and can take 15 to 30 days depending on the destination. Note that distilled water is required for diluting samples and calibrating devices but is not provided in the kit. While the kit offers a reliable estimation of iron levels, it is recommended to confirm results through certified laboratory testing for determining the suitability of a water source for drinking.The ffem Total Iron test kit provides you with a means of monitoring water for Iron rapidly. The test used is a colorimetric test using a two liquid reagents. The reagents induces a colour change in the sample depending on the concentration of Iron present.
You can get fairly accurate readings of this colour change using the ffem match Android app. You will need to calibrate your Android phone first, and calibration standards are provided with the kit. Alternatively you can read semi-quantitative results using the colour card provided using your visual judgement, or using the app.
Since the kit contains chemical reagents, they are shipped by road, delivery could take between 15 and 30 days depending on the destination.
You will also need distilled water (not supplied with the kit) to dilute samples and to calibrate phones.
Disclaimer: While the reagent and the app are a fairly accurate way of estimating Iron in drinking water, please have water sample tested at certified laboratories while deciding on the fitness of a water source for drinking purposes.
