Gas Analyzer Systems

This category lists industrial gas analyzers and complete gas analyzer systems for process control, combustion and gas quality measurement. It includes oxygen analyzers, H2S and sulfur analyzers, process gas chromatographs, moisture and hydrocarbon dew point analyzers, laser-based instruments and portable flue gas analyzers. The products come from Galvanic, Applied Analytics, AMETEK, Servomex and ABB, among others. Seven Star LLC supplies them from Muscat to plants in Oman and neighboring countries.

Types of gas analyzer in this category

• Oxygen analyzers: paramagnetic, zirconia and electrochemical instruments for percent, trace and ultra-trace O2, fixed and portable, from Servomex, Southland Sensing, Systech and Teledyne.
• Sulfur analyzers: H2S analyzers for natural gas and fuel gas, plus tail gas and sulfur pit analyzers for sulfur recovery units.
• Gas chromatographs for BTU, heating value and hydrocarbon composition.
• Moisture and dew point analyzers from Michell Instruments, Panametrics and BARTEC.
• Tunable diode laser analyzers for H2S, CO2 and H2O in natural gas.
• Portable flue gas analyzers from Testo for burner and boiler checks.

How to choose an industrial process gas analyzer

Start from the component and its range, then look at everything else in the stream. The background gas decides which measuring principle will work, because most principles respond to more than one species. A zirconia cell, for example, reads low when the sample contains combustibles, and an infrared bench needs compensation when another gas absorbs in the same band. Sample pressure, temperature, dust and liquid carry-over decide how much sample conditioning is needed in front of an extractive analyzer, or if an in-situ laser measurement across the duct is the simpler route.

Analyzers mounted in classified areas are normally built with flameproof enclosures or a purged and pressurized cabinet and carry ATEX or IECEx certification. Sales gas measurements in the GCC usually follow the gas quality specification of the pipeline operator, so state the method or standard written in your specification.

What to send for a gas analyzer quotation

Give us the gas to be measured and its range, the full stream composition, sample pressure and temperature, the area classification, the required outputs and the power supply available. If you are replacing an existing analyzer, the model and serial number are the most direct route to a correct offer. We check the configuration against the manufacturer documentation, propose the manufacturer’s successor when a model is obsolete, and provide the datasheet and the manufacturer’s certificates on request.
