What Analytical Industries does

Analytical Industries Inc. (AII) designs and manufactures high-performance electrochemical oxygen sensors and gas analyzers from its headquarters and manufacturing facility in Pomona, California. The company is a wholly owned brand of DwyerOmega, a diversified process sensing and measurement conglomerate, and operates with a global footprint backed by local sales and service offices, distributors, and channel partners. Its core technology is a proprietary line of galvanic electrochemical oxygen sensors built around a lead cathode and zinc anode with a liquid or gel electrolyte and a permeable membrane; these sensors generate an electric current proportional to oxygen concentration without requiring external power. AII complements the galvanic platform with zirconia-based sensors for combustion control and embeds deterministic sensor-fusion algorithms (e.g., Trimix 4001) that combine inputs from oxygen, helium, temperature, pressure, and humidity sensors. Product capabilities span ultra-trace (ppb) through 100% oxygen purity, with sensor lifetimes up to 60 months and T90 response times as fast as 3 seconds on certain PPM models.

AII serves four primary customer segments: industrial process control (oil and gas, petrochemicals, specialty gases, semiconductor fabrication, natural gas and biogas H2S analysis), medical OEMs and providers (ventilators, anesthesia machines, incubators, oxygen monitors, breathing-gas mixers), the diving industry (rebreathers, Nitrox and Trimix analyzers, technical and commercial divers), and OEMs requiring replacement sensors compatible with third-party analyzers. The portfolio is organized into galvanic oxygen sensors (GPR, PSR, XLT series), industrial and process analyzers (GPR-1500/2500, GPR-2800, GPR-1900/2900), portable and handheld analyzers (AII-2000, AII-3000, PalmO2, Trimix 4001, Palm CO), H2S analyzers (GPR-7100), combustion control analyzers (Oxyflex), and dedicated medical and diving replacement sensors. All products are manufactured exclusively in the USA.

The business model is overwhelmingly hardware-driven: AII sells sensors, analyzers, accessories, and replacement parts as physical goods, supplemented by a custom sensor design service for OEMs requiring tailored cabling, connectors, outputs, or housings. Pricing is uniformly quote-based rather than publicly disclosed, with multi-year contracts common in industrial and medical deployments. Distribution is hybrid — direct sales via website quote requests and a sales force, distributor and channel partners internationally, and a US-only direct-to-consumer e-commerce store for diving products. Customer acquisition is supported by content marketing through a blog and resource library, LinkedIn and YouTube channels under the DwyerOmega brand, and industry event participation. Regulatory and certification credentials (FDA approval, MDSAP, ISO 13485, ISO 9001, ATEX, IECEx, UKEx, MET HazLoc) are central to the value proposition, particularly in medical and hazardous-area industrial markets.

Core offering

Analytical Industries designs and manufactures high-performance electrochemical oxygen sensors and gas analyzers for industrial process control, medical life-support systems, and professional diving applications. The product portfolio includes galvanic electrochemical sensors (GPR, PSR, XLT series), handheld and portable oxygen analyzers (AII-2000, AII-3000, PalmO2, Trimix 4001), process and hazardous-area oxygen transmitters (GPR-1500/2500, GPR-2800, GPR-1900/2900), H2S analyzers, and zirconia-based combustion control analyzers, with measurement ranges from parts per billion to 100% O2 purity.

Product overview

Analytical Industries (AII) offers a comprehensive portfolio of high-performance oxygen sensors and gas analyzers for industrial, medical, and diving applications. The product line is organized around three core technology areas: (1) Galvanic Electrochemical Sensors (GPR, PSR, and XLT series) that provide PPM-level trace detection through 100% purity measurement; (2) Oxygen Analyzers including portable handheld units (AII-2000, AII-3000, PalmO2, Trimix 4001), process/transmitter analyzers (GPR-1500/2500, GPR-2800, GPR-1900/2900), hazardous area certified analyzers, and specialty analyzers for H2S and combustion control; and (3) Medical and Diving replacement sensors. The analyzers leverage the proprietary sensor technology, with most featuring user-friendly interfaces, data logging, and easy calibration. Products are manufactured exclusively in the USA with global certifications (FDA, MDSAP, ISO 13485, ATEX, IECEx).

Direct peers

• Drägerwerk: Dräger is a global leader in medical and safety gas detection, including medical oxygen sensors for ventilators and anesthesia machines — directly competing with AII's medical oxygen sensor line. The company shares the same FDA/ISO 13485 medical regulatory profile and the same industrial/military safety customer base.
• MSA Safety: MSA manufactures portable and fixed gas detection instruments including oxygen sensors and monitors for industrial safety, fire service, and hazardous area applications. Overlaps directly with AII's industrial oxygen analyzers and AII-3000 series portable units used in personnel safety monitoring.
• Servomex: Servomex (a Spectris company) is one of the most direct competitors to AII, manufacturing oxygen, combustion, and specialty gas analyzers for industrial process, medical, and emissions applications. Competes head-to-head in trace and percent oxygen measurement with overlapping product ranges (ppb to 100% O2).
• MAXTEC (ICU Medical): MAXTEC, now part of ICU Medical, is one of the closest direct competitors in medical oxygen sensors and analyzers used in ventilators, anesthesia, and respiratory care. Competes in essentially the same FDA-cleared medical oxygen sensor market that AII serves.
• Teledyne Analytical Instruments: Teledyne's analytical instruments division manufactures oxygen and other gas analyzers for process, emissions, and laboratory markets. Direct competition with AII's GPR series trace and percent oxygen analyzers in industrial process control applications.

Broad incumbents

• Mettler-Toledo: Mettler-Toledo's Process Analytics division produces dissolved oxygen and gas analyzers used in pharmaceutical, biotech, and chemical process industries. While its primary process analytics focus is on liquid-phase measurement, it competes with AII in regulated-process gas purity verification and shares similar global certification requirements.
• Emerson Electric (Rosemount): Emerson's Rosemount and analytical businesses provide broad process measurement and gas analysis solutions for refineries, chemical plants, and power generation. Overlaps with AII's industrial process oxygen analyzer portfolio in similar hazardous-area applications but as a much larger diversified automation vendor.
• Honeywell International (Analytics): Honeywell's Analytics division (including BW Technologies and Sieger) offers a broad portfolio of fixed and portable gas detectors including oxygen. As a multi-gas, multi-billion-dollar incumbent, Honeywell competes with AII in industrial and safety gas detection but also serves as a customer whose analyzer installed base AII targets with replacement sensors.
• Yokogawa Electric: Yokogawa provides a broad process analytics portfolio including oxygen and combustion gas analyzers used in refineries, chemical plants, and power generation. Overlaps with AII's industrial process oxygen transmitters in similar hazardous-area certified use cases.

Emerging players

• Oxigraf: Oxigraf designs and manufactures oxygen analyzers based on tunable diode laser absorption spectroscopy (TDLAS) for medical, industrial, and environmental applications. A smaller, more specialized competitor than AII but competes in adjacent oxygen measurement markets with a different technology base.
