Hach Iron Test Strips (Total Dissolved Iron), 0-5 mg/L, 2745325

Works good for well and city water test, very basic.

Easy to use, produces results consistent with expectations.

In general it's fine to test my home water filtration system. I would like to have it be more accurate as it was still showing the lowest amout of Iron when testing distilled water.

I bought this because I bought an iSpring 3 stage filter and the iSpring filter is supposed to take out iron. The test result is a typical color chart. So right after I got the test and had the iSpring filter running a few days I tested the water and for no iron it should be white but it had a slight pink tint indicating between 0.0 and 0.15 PPM Iron. Then I got the idea to test distilled water (from Kroger) and when I test the distilled water I see the same slight pink color as with water that has been through my iSpring iron filter, per the color chart it should be pretty much white. So I'm not convinced the test has great results to show 0 PPM iron which it should show for the distilled water. So now I think the iSpring filter works well and I'll do 2 tests with water from the filter and with distilled water to be sure I'm at pretty much 0 PPM iron if the 2 tests are pretty much the same color. It says to read the results immediately and I feel like I do that and the color is not white but has a pink tint which puts it between 0 and 0.15 PPM iron.

I had originally purchased one of those kits with the strips that have like 16 different tests. The one I purchased was a total scam. It read the same, whether I used it in treated or untreated water - even distilled water. This test is a bit more involved - not hard, but takes a couple of steps. It gave me what I believe are accurate results - at least predictable given the level of each water sample treated.

Tried twice they failed twice to deliver fresh chemicals. When fresh this test kit should not expire for about two years. The key word being fresh. Hach tends to send out kits with less than 10 months expiration.

I used this on my well water. Not sure of the overall accuracy but I assume that it is okay. I tested my water directly from the well and after going through my treating system and it was 0.6 mg/l directly from my well and 0 mg/l after treatment. Whether these numbers are correct or not is debatable, but at least it appears to be in the right direction.

Purchased this to verify iron content before and after treatment. Our results matched lab numbers and now I'm confident that we can calibrate our treatment options without paying $120 for each lab test.
