H2S - SO2 Analyzer, Model 450i - 26801 Hydrogen Sulfi de - Sulfur Dioxide Analyzer, Model 450i

Pulsed fl uorescence gas analyzer

Utilizing pulsed fl uorescence technology the Model 450 i H2S and SO2 analyzer operates on the principle that H
2 S can be converted to SO
2 . As the SO
2 molecules absorb ultraviolet (UV) light and become excited at one wave- length, the molecules then decay to a lower energy state emitting UV light at a different wavelength. Specifi cally,H Key Features Pulsed excitation and intensity stabilization

2 + hv 2 The pulsing of the U.V. source lamp serves to increase the optical intensity whereby a greater U.V. energy throughput and lower detectable SO Temperature stabilization reaction chamber Stable, long-life UV source
2 concentration are realized. Refl ective bandpass fi lters, as compared to commonly used transmission fi lters, are less subject to photochemical degradation and are more selective in wavelength isolation. This results in both increased detection specifi city and long term stability. This state-of-the-art gas analyzer also offers features such as an ethernet port as well as fl ash memory for increased data storage. Ethernet connectivity provides effi cient remote access, allowing the user to down- load measurement information directly from the instrument without having to be on-site.You can easily program short cut-keys to allow you to jump directly to frequently accessed functions, menus or screens. The larger interface screen can display up to fi ve lines of measurement information while primary screen remains visible. Superior zero stability
