AMETEK-930 H2S in Sulfur Pit Analyzer
Overview
Using proven ultraviolet (UV) technology, the AMETEK 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 the smoldering fire level of SO2.
Engineering & Design
The 930 samples the vapor space gas using reliable UV technology, and the sampling system has a sulfur knock-out at the probe to eliminate entry of excess sulfur vapor or liquid into the system. The ASR900 advanced sulfur reduction sampling probe option uses a temperature-controlled sulfur condenser, providing sulfur vapor control at the sample point so that no plugging occurs in the sample lines and analyzer.
The dual-beam configuration, combined with the reference measurement, ensures low noise performance with minimal baseline and span drift. 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.

For sulfur pit safety, the AMETEK 930 H2S analyzer is the established instrument, and Seven Star LLC supplies the AMETEK 930 H2S analyzer with probe options for your installation.
The AMETEK 930 H2S analyzer measures the hydrogen sulfide concentration in the sulfur recovery unit with the solid state sensing element. The analyzer draws the sample from the sulfur pit and the acid gas line and the sensor produces the signal proportional to the H2S content of the gas. The control unit displays the reading in ppm and provides the alarm outputs for the plant operation. The analyzer is certified for the hazardous area of the SRU.
The sample system of the analyzer includes the filters and the flow control to keep the sensor clean. The calibration is performed with the certified span gas and the zero gas, and the reading is verified on the monthly schedule. The spare parts of the 930 analyzer are available with the sensor and the electronic board of the unit.
The 930 analyzer is used in the sulfur recovery unit for the acid gas and the tail gas monitoring, and the sample conditioning removes the entrained liquid from the line. The control unit provides the local display and the 4-20 mA outputs for the SRU control system. The maintenance covers the sensor replacement and the filter cleaning on the routine schedule. The spare sensor and the electronic board are available for the unit.
Why Seven Star LLC
Seven Star LLC supplies the AMETEK 930 H2S analyzer for sulfur pit safety projects across the Gulf, with verified specifications and technical support. Our team assists with probe selection, installation planning, and integration with plant safety systems.
We serve hydrocarbon processing and sulfur recovery customers with reliable B2B supply of analyzers throughout the GCC.
Installation & Operation
The analyzer is installed with the sample probe in the vapor space of the sulfur pit, and the sulfur knock-out at the probe prevents excess sulfur from entering the sample system. The ASR900 probe option adds the temperature-controlled sulfur condenser for plugging protection.
The dual-beam optics maintain the calibration stability between checks, and the simultaneous H2S and SO2 measurements feed the plant alarm system for the LEL and smoldering fire levels.
