We recently learned that Filter Water, an online distributor of drinking water quality improvement and water testing products, has expanded the number of SenSafe Test Kits to include Ida’s Iron, a dual range test strip that can detect ferrous iron levels as low as 0.005 ppm and as high as 50 ppm in under a minute.

Ida’s Iron specifically reacts with (ferrous) dissolved iron (in the +2 state) without interference from other heavy metals such as copper, silver, mercury, lead or chromium.

For applications where fast, accurate field testing for low levels of Fe+2 matters, Ida’s Iron provides a solid solution and allows you to say, “goodbye” to time-consuming wet-chemical kits that may require specialized training or equipment.

Features of Ida’s Iron include low detection range, easy testing procedures, test times under one minute, no need for glassware, and low test reagent concentrations.

Below you will see a sample of the Ida’s Iron color chart and label:

Ida’s Iron Check Water Test Specifications:

  • Sensitivity: 0, 0.005, 0.01, 0.03, 0.06, 0.1, 0.3, 1.0, 2.0, 5.0, 10, 20, 50 ppm (mg/L)
  • Test time: 45 seconds
  • 25 test strips in a package

Note: To test for total iron, you will want to use a test kit such as the Visual Iron Test Kit which detects both ferrous iron and ferric iron.
