Description

GAS211 Sulphide Ions Gastec Soluble Ion Detector Tubes

The Gastec Sulphide Ion in Solution Detector Tube No. 211 provides an accurate, cost- effective, quick and easy method for detecting sulphide 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 colour-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. The Gastec sulphide ion tube requires no colour comparison chart or laboratory equipment to determine results. Additionally, the colour- 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 sulphide 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 sulphide ion tube, no mixing of chemicals is required, minimising potential errors.

To measure, simply immerse the detector tube in a sample of liquid (placed in a beaker or other container). Anyone can measure concentrations quickly, easily and accurately on site.
