AMETEK-930 H2S in Sulfur Pit Analyzer

Using proven ultraviolet (UV) technology, the 930 identifies potential safety risks in sulfur storage locations through simultaneous hydrogen sulfide (H₂S) and sulfur dioxide (SO₂) measurements.

Capable of stable, sensitive measurements ranging from parts-per-million (ppm) to percentage levels, the analyzer offers output alarms for the lower explosive limit of H₂S and smoldering fire level of SO₂.

The 930 analyzer samples the vapor space gas using reliable UV technology. The sampling system has a sulfur knock-out at the probe to eliminate entry of excess sulfur vapor or liquid into the system.

Sharing a common design with the 900 (air demand) and 910/920 (stack gas) analyzers, the 930 provides simultaneous safety measurements for sulfur recovery and de-gassing in the hydrocarbon processing industry.

MINIMAL BASELINE AND SPAN DRIFT
The 930’s dual-beam configuration, combined with the reference measurement, ensures low noise performance with minimal baseline and span drift. Measurements from ppm to percent level are possible.

SIMULTANEOUS MEASUREMENTS
A multi-component UV analyzer, the 930 is configured to measure both H₂S and SO₂ in the sulfur pit at the same time.

ASR900 PROBE OPTION
The ASR900 advanced sulfur reduction sampling probe uses a temperature-controlled sulfur condenser, providing sulfur vapor control at the sample point. This ensures no plugging will occur in the sample lines and analyzer.
