Iron Test Strips, 0-100 ppm [Vial of 50 Strips] for Measuring Free Soluble Iron (Fe2+ and Fe3+)

These Iron Test Strips work very well. I installed a new water softer and needed to know the Iron content both before and after treatment. These test strips allowed me to dial in the water softer to completely remove the Clearwater Iron from my water. Good Product!

This product works well for iron that is not dissolved in the water, the test is accurate, and easy to use. Had a small issue and the seller provided excellent service and resolve the problem quickly. I recomed this product and company.

Although I would be glad to have 0 Iron, I would have to disagree with this test. I took some sample from the faucet after my water pump, a couple of minutes after it showed brownish in color. Sample was clear. Result was no Iron. I went drastic and mixed rust with water - still 0 Iron. I then rubbed it in wet rust, STILL 0 IRON....Seems like I was just wetting a wetted filter paper...

Easy to use. Not the most sensitive, but well-quantifiable and well-specified and just sensitive enough to help me realize that my tap-water has less iron than I worried it did.

This razor provides very nice shaves with good durability.

Tested what I was looking to test.

Easy to use. Inexpensive. And seem to be accurate...I don't have any way to test accuracy.

Does not work at all. Our unfiltered water is brown and has iron in it you can see and it still reads 0. Don't buy this.
