ProTech903™ Tape-Based H2S / Total Sulfur Analyzer
Colorimetric tape analyzer for H2S, total sulfur, arsine, phosphine, phosgene and chlorine.
Key Features
- 5 ppbv sensitivity, ranges from 0-100 ppbv to 0-1 ppmv
- Five- to 14-week tape lifetime for extended hands-off operation
- 10 quick-status LED indicators plus large LCD display
- Smart self-diagnostics with remote access
- User-friendly Windows-based software with graphical interface
- Solar power option for remote-area operation
- Multi-stream capability
Overview
The Galvanic ProTech903 is a proven colorimetric paper-tape analyzer delivering fast, highly sensitive measurement of H2S and total sulfur, with dedicated variants also available for arsine, phosphine, phosgene, and chlorine. It outperforms competing methods in the critical 0-15 ppmv range and is interference-free and not matrix-dependent.
Working Principle
Sample gas reacts with a reagent-impregnated paper tape; the resulting colorimetric stain is measured optically and converted to a concentration reading. A proprietary Tape Assurance System keeps tape feed and reaction consistent for trouble-free, long-run operation.
Applications
Benefits
- Low detection limits outperform other analytical methods at 0-15 ppmv
- Interference-free, not matrix-dependent
- Lowest total cost of ownership among tape-based analyzers
- One platform family covers H2S/total sulfur, arsine, phosphine, phosgene and chlorine
