The one-dip Insta-TEST® Iron test strip formula eliminates the need to pre-treat the sample with a reduction tablet prior to measuring Iron with a test strip. The Iron strip makes the testing process simpler with just one dip of the strip into a pool or spa before matching the reaction to a color chart (0, 0.3, 0.5, 1, 3, 5 ppm) on the bottle.
Ideal for testing your water's iron content prior to purchasing one of our 14 Stage Biocompatible Water Purification Systems. This one-of-a-kind testing strip offers stable color development with very distinct colors. There are 25 strips per bottle and packaged in a unique, hinged, waterproof PopTop bottle with a desiccant liner that protects the iron water test strips from moisture intrusion. This product includes trilingual (English, Spanish, French) instructions.

Iron test strip
It gave me the info that I needed (along with hardness strip) to set my water hardness for my water softener.
