Sulfide Ion Detector Tubes

The Gastec Sulfide Ion in Solution Detector Tube No. 211 from Nextteq detects sulfide ion levels in solution. With the easy-to-use system, direct-reading tubes produce a quantitative color-stain that quickly pinpoints problem areas in two to three minutes. The calibration scale, printed directly on each tube, provides on-the-spot results. The Gastec sulfide ion tube requires no color comparison chart or laboratory equipment to determine results. The colorstain ends with a clearly defined line of demarcation to further eliminate confusion.
