GAS-1051 Sulfur Dioxide & Hydrogen Sulfide Analyzer

The GAS-1051 analyzer combines pulsed fluorescence detection with an internal catalytic converter to sequentially measure H2S and SO2 in the range of 0 – 2 / 0 – 20 ppm respectively with a detection limit of 0.3 ppb.

The measurements involve two cycles:

1. H2S is measured by passing the sample through an internal SO2 scrubber which removes any SO2. The H2S is then converted to SO2 using the internal converter, and measured using the fluorescence technique.
2. SO2 is then sequentially measured by bypassing the SO2 scrubber and converter, and using the fluorescence technique to measure only the SO2 concentration.

Approvals:
Based on the GAS-1050 analyzer which has the following approvals:

• US EPA approval (EQSA-0809-188)

Benefits:

The Met One range of gas analyzers have been designed using experience and knowledge gained from operating large air quality monitoring networks for more than 40 years. The result, instruments that integrate seamlessly into continuous monitoring networks.

• Reliable performance backed up by a two-year warranty.
• Internal thermal catalytic H2S to SO2 converter.
• User selectable measurement of SO2/H2S, H2S, or SO2 only.
• Minimize time spent on site performing maintenance through superior remote instrument control, diagnostic viewing, and calibration.
• Comprehensive data logging and remote viewing of over 200 operational parameters.
• Versatile interfacing through RS232, USB, analog, TCP/IP, and optional Bluetooth.
• Easier setup through an intuitive menu system with “Quick Menu”, advanced GUI, and a large keypad with tactile keys.
• Instant display of operational status using illuminated traffic lights on the front panel.
• Removable flash memory stores 10 years of data, including up to 12 individual parameters and event logs. Operational parameters can also be transferred to memory for easy retrieval.
• Latest firmware updates can easily be installed using the USB flash memory drive.
• Programming, viewing, downloading, and emailing of data is made even simpler using optional Bluetooth connectivity combined with Android App.
• Enhanced operator safety through the use of 12 VDC internal voltages.
• Reduced cost of spare parts, accessories, and consumable items through extensive use of standard components across the Met One analyzer range.
• Rack slide design makes accessing internal components and removing the analyzer from a rack cabinet easy.
• AQMS power usage can be reduced due to the instrument’s low power demand and its ability to operate over a wide temperature range.
