Buy Indigo® residual test strips for drinking water or organic food preparation equipment to determine residual free chlorine levels. They are ideal for anyone who is concerned about detecting trace (residual) levels of free chlorine to meet USDA or California organic certification regulations
The strips are very easy to use. Simply place a drop of water on the indicator pad of the test strip and then firmly press it against the food handling equipment, tables or skin of the fruit and vegetables themselves. If there is chlorine present, the strip will change color & can be compared to the color chart after 30 seconds.
You can also test for chlorine in drinking water if you have concerns about this. We have tried it on the water in our area & the chlorine is below the measurable limit of the strip.

Second time ordering this product. Very satisfied with test strip quality. Fast shipping is available and very convenient.
Glad we could help.
I ordered several of your test strips. They came promptly and were what I ordered. I have used a few of the strips and they seem to work OK.
Glad we would help with your residual level testing. Thank you for review.
I personally have not used the test strips. I buy for purchase order request. I'm a buyer. But upon reading about them they sound great! Thank you, Rueben
