Dissolved Gas Analyzer Market Size

The dissolved gas analyzer market was estimated at USD 578 million in 2024. The market is expected to grow from USD 608.6 million in 2025 to USD 1.05 billion in 2034, at a CAGR of 6.3% according to latest report published by Global Market Insights Inc.

The market for dissolved gas analyzers (DGAs) focused on technology capable of detecting and analyzing gases dissolved in transformer oil; measurement of the dissolved gases provides necessary information for evaluating the condition and health of power transformers. DGAs are important systems to detect potential issues early enough to allow maintenance to be carried out and potentially avoid risk of failure of the transformer. As power infrastructures around the world ages, in both utility and industrial applications, DGAs are being increasingly adopted to help monitor health and ensure grid stability whilst allowing the development of planned maintenance schedules. With the development of planned maintenance schedules, organizations can continually improve operational reliability while decreasing downtime which is critical to maintaining an uninterrupted supply of power.
 

Continuous awareness of the importance of doing condition monitoring of power transformers is also advancing the market. These changes in behaviors also validate the need for diagnostic gas analysis (DGA) for long term reliability and sustainability of power infrastructures, particularly in the world where infrastructures are aging. Several factors are aiding in the growth of the DGA market. Continually increasing safety regulations are compelling industries to invest in more sophisticated monitoring solutions to help meet benchmark standards or improve safety and reduce risk. The increasing market for predictive maintenance solutions is further promoting investment in DGAs, as these systems will provide actionable results that can be used to assess transformer health.
 

Technological advancements have also been a major contributor to the DGA market. Emerging sensor technology, including photoacoustic spectroscopy and gas chromatography, enhance gas detection in terms of sensitivity and precision. These technologies will allow for greater sample analysis, leading to enhanced management and maintenance practices. Therefore, the adoption of advanced technologies is anticipated to increase growth in the market throughout the forecast period and form an essential part of power systems in the generation and transmission segments.
 

Dissolved Gas Analyzer Market Trends

The industry is evolving and adapting rapidly aimed at improving accuracy, reliability, and the integration of data into smart grid operations.
 

• Gas Separation and Detection Technology: While gas chromatography (GC) remains the accepted laboratory standard, online monitors are increasingly based on photo-acoustic spectroscopy (PAS), which is stable and does not have consumable gas as a precursor. We expect that new sensor technologies based on solid-state (e.g., MEMS) sensors will offer lower costs and form factor reduction in future devices.
   
• Embedded AI and Edge Computing: New DGA monitors are under development with onboard processing capabilities providing substantial computational capabilities to run AI algorithms "at the edge" for immediate diagnostic and notification capabilities without continual connection dependence on the cloud/server, improving response time and security.
   
• Integrated Communication Protocols: Modern DGA monitors are pursuing native enforcement of built-in standards for substation automation, like IEC 61850, DNP3, and Modbus, which means easier (plug-and-play) integration with SCADA systems and digital substations which can reduce commissioning time and complexity.
   
• Non-Invasive - Membrane-Based Extraction of Gases: Innovations continue in extraction methods to isolate dissolved gases evolving in transformer oil and more recently new advanced membrane extraction technologies will provide enhanced extraction with better efficiency and stability than older headspace/vacuum extraction methods, improving measurement reliability and accuracy.

Based on product type, the dissolved gas analyzer market is divided into multi-gas system, single gas systems, and others. The multi-gas system segment accounted for around 62% market share in 2024 and is expected to grow at a CAGR of over 6.4% through 2034.
 

• Multi gas analyzers are modern instruments optimized for the measurement and analysis of many gases simultaneously in different conditions. Multi gas analyzers use advanced sensor technologies to identify and quantify gases, including oxygen, carbon dioxide, carbon monoxide, methane, and volatile organic compounds (VOCs). Multi gas analyzers are the ideal technology for providing accurate, real-time data about air quality and safe operational environments in industrial and environmental conditions.
   
• Multi gas analyzers can be used in a variety of applications, including environmental monitoring, industrial safety, and process control. In environmental monitoring, gas analyzers quantify and monitor levels of air pollution with continued regulatory compliance. In industrial safety, gas analyzers identify and detect hazardous gases to reduce incidents; in addition to providing real-time data. In addition to monitoring safety and environmental compliance, multi gas analyzers can also monitor process control; identifying the levels of gases including CO/CO2 and providing real-time data for improved efficiency in ignition and combustion performance in boilers, engines, thermal oxidizers, gas combustion engines, and diesel engines.
   
• Multi gas analyzers have become necessary tools across industries due to their accuracy, flexibility, and reliability to monitor and report gases. They offer compliance with environmental and safety regulations while showing high impact on industrial efficiency. The demand for multi-gas analyzers will continue to increase, furthering their purpose in multiple applications, as industries remain focused on safety and sustainability.

Based on protocol systems, the dissolved gas analyzer market is segmented into modern digital protocols, legacy protocol systems, and others. The modern digital protocols segment dominates the market with 63% share in 2024 and is expected to grow at a CAGR of over 6.4% from 2025 to 2034.
 

• Modern digital protocols are dominating the market because they provide faster, more secure, and more scalable integration of monitoring systems into an increasingly digital and automated power system.
   
• Protocols such as IEC 61850 and DNP3 allow for real-time data exchange, event-driven communications, and interoperability between different devices and platforms from multiple vendors all essential to smart grids, digital substations, and predictive maintenance.
   
• As opposed to legacy systems, today’s protocols support Ethernet-based networking, cybersecurity capabilities, and remote diagnostics ideal for utilities and industries looking to improve reliability, minimize downtime, and enable cloud-based analytics. And the continued acceptance of such protocols within the electric sector is indicative of a larger movement of digital transformation.
   

Based on distribution channel, the market is segmented into direct sales and indirect sales.
 

• In the market for DGAs, indirect sales serve as the primary sales channel because of the specialized nature of products which target specific industries. The precise split in market share between direct and indirect sales is not provided, but indirect channels have become the dominant approach to reaching a wide customer base.
   
• Indirect channels are specifically effective in utility industries, power generation, oil & gas, and chemicals, in which highly technical operations require specialized solutions and deep knowledge base. The indirect channel for sales is driven by efficiency in bringing manufactures to end users.
   
• Specialized industrial suppliers, technical service providers, and distributors have a crucial role in this environment, and companies like General Electric utilize large distribution networks to access end-users.
   
• These intermediaries have built trusted customer relationships, market knowledge, and the capability to sell, install and service DGAs or more complex equipment. Using indirect channels allows manufacturers to penetrate new or niche markets, in a timelier manner, with less fixed costs, and more scalability and growth opportunities, all of which are critical during the development of new markets.
   
• Typically, direct sales are reserved for large or strategically positioned customers, where manufacturers want to exert control over the branding and customer-relationship site. Nevertheless, manufacturer indirect channels provide advantages that are vital for a broad market penetration opportunity.
