These test papers do not come with a color chart but the presence and relative concentration of hydrogen sulfide is readily apparent. While normally specified with a 5ppm detection sensitivity, 1-3ppm appears to sufficient to slowly cause the white test paper to turn grey. As the concentration approaches the dangerous level of 400ppm, the change proceeds very rapidly.

The test strips from Indigo are top notch. They are always competitively priced and shipped on time. The best part of dealing with Indigo is that they stay on top of their products. We had a bad batch of strips arrive in the past but before we could figure it out the hard way, Indigo had identified the issue and had a replacement order already in the mail to us. Pretty hard to beat that kind of customer service.
