Solution Tubes for Measuring Sulfide Ion in Wastewater Applications


TAMPA, FL – The Gastec Sulfide Ion in Solution Detector Tube No. 211 provides an accurate, cost- effective, quick and easy method for detecting sulfide ion levels in solution. Determining a more efficient manner of testing for this has become paramount, especially in the wastewater treatment industry.

With Gastec’s easy-to-use system, direct-reading tubes produce a quantitative color-stain that quickly pinpoints problem areas in just 2 to 3 minutes. The calibration scale, printed directly on each tube, provides on-the-spot results that are easy to read. This system saves you time and money by avoiding lengthy laboratory turnaround time. Unlike the tedious Methylene Blue testing method, the Gastec sulfide ion tube requires no color comparison chart or laboratory equipment to determine results. Additionally, the color- stain ends with a clearly defined line of demarcation to further eliminate confusion, increasing the accuracy of the results.

The only equipment required for testing sulfide ions is the Gastec No. 211 detector tube and a clean container, saving money and eliminating the hassle of transporting cumbersome equipment. The system is so easy-to-use technical training is not necessary to perform tests accurately. The detector tubes are available in four different ranges for more specific measuring, with a total range of 0.5 to 1000 ppm. With Gastec’s sulfide ion tube, no mixing of chemicals is required, minimizing potential errors.  

I addition to the Sulfide Ion Solution Detector Tube No. 211, Gastec manufactures other Sulfide Ion Tubes that can measure Sulfide in Solution starting at 0.5 ppm up to 1000 ppm as well as solution tubes for Ozone, Bromide, Chloride, Free Residual Chlorine, Mercury, Chromium, Iron, Copper, Zinc, and Nickel.
