Industrial Test Systems eXact 484003 Cyanide ReagentStrip Test Kit, 2 Minutes Test Time, 0.05-200 ppm Range (Pack of 50)

This test was very use to perform. Strips are good for more than a year. I am happy with my purchase and will continue to use these strips. Fast shipping and great price!

Got the answers that I needed to get, however there needs to be picture examples of the colors. I had to read several guides to see how vivid the results were to know if it was working. You have to look at the square vessel at an angle in broadcast light, white light specifically. Id put a picture but it is really hard to see the changes in color visibly let alone in a picture for example.

This came with a tiny print out of black and white instructions to match the color to. The printing on the side of the container is in color, but all figures are too small to read.

There was a cyanide leak at a nearby factory. Though they did not feel as homes/water would be affected, I bought these strips for a peace of mind. I’m thankful for these tests and monitored our water frequently. Affordable and easy to use.
