ffem - Android App Based Fluoride Test Kit
The ffem Fluoride Test Kit offers a practical solution for quickly assessing fluoride levels in drinking water. Utilizing a colorimetric method with a modified SPADNS reagent, this kit facilitates the detection of fluoride concentrations through a visible color change in the sample. Users can obtain precise readings with the ffem match Android app, which requires prior calibration with provided standards, or by using the accompanying color card for semi-quantitative analysis. While the kit is particularly effective for on-the-spot assessments, it is recommended to confirm fluoride levels through certified laboratory testing to ensure water safety. The package includes necessary reagents, although users must source distilled water independently for sample dilution and phone calibration. Delivery of the kit, which involves road transport due to the chemical content, typically occurs within 15 to 30 days.BIS standards for water limits Fluoride in drinking water to 1 mg / l, or 1 ppm.
The ffem Fluoride test kit provides you with a means of monitoring water for Fluoride rapidly. The test used is a colorimetric test using a modified SPADNS reagent. The reagent induces a colour change in the sample depending on the concentration of Fluoride 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 Fluoride in drinking water, please have water sample tested at certified laboratories while deciding on the fitness of a water source for drinking purposes.
