Dräger™ Tubes détecteurs à court terme - Mercaptan
Description
The Dräger Mercaptan 20/a detector tube is designed for the rapid and precise measurement of mercaptan gas concentrations. The system uses glass tubes containing a chemical reagent that changes color in the presence of the target analyte, allowing for semi-quantitative concentration readings.
- Gas Measured: Mercaptan
- Standard Measurement Range: 20 to 100 ppm
- Number of Strokes (n): 10
- Measurement Duration: approx. 2.5 min
- Standard Deviation: ±10 to 15 %
- Color Change: White to yellow-brown
- Operating Temperature: 0°C to 50°C
- Operating Humidity: 3 to 30 mg H2O/L
- Measurement Principle: 2 R-SH + Cu²+ → Cu(RS)² + 2 H+; Cu(RS)² + S → yellow-brown Cu-compound
- Compatibility: Used with Dräger Accuro™ bellows pump or automatic pumps like Accuro 2000 and Quantimeter 1000
- Cross-Sensitivity: Higher alkyl mercaptans (propyl- and butyl-mercaptan) are indicated with similar sensitivity. Measurement is not possible in the presence of hydrogen sulfide, as it is indicated with approximately double the sensitivity.
- L’extension de la plage de mesure indiquée est possible pour certains tubes détecteurs. Appelez Fisher Scientific™ le 1-800-772-6733 pour plus d’informations.
- Certifié Safety Equipment Institute (SEI).
