930 H2S in Sulfur Pit Analyzer was developed for sulfur pit storage applications. The 930 has been field proven as one of the industry’s most reliable instruments for monitoring H2S and SO2. The analyzer uses a proprietary high resolution UV technology in a dual beam, multiple wavelength configuration. Resolution better than 0.02 nm is provided by high intensity, line source lamps. These sources emit at a fixed wavelength, providing great measurement stability, and emit low total power, removing the potential for sample photolysis. The dual beam configuration, combined with the reference measurement, ensures low noise performance, with minimal baseline and span drift.
The 930 analyzer samples the vapour space gas using proven ASR Probe technology. The sampling system has a sulfur knock-out at the probe to eliminate entry of excess sulfur vapour or liquid into the system. The sample is transported through an electrically traced sample line.
Features
- Simultaneous, accurate measurement of both H2S and SO2
- Output alarms for H2S (LEL) and SO2 (smoldering fire)
- Common design with Model 900 (air demand) and Model 910 (stack gas)
- Exceptional baseline stability
- Improved sample conditioning via ASR Probe
