What Cosasco does

Cosasco, legally Rohrback Cosasco Systems, Inc., is a 75-year-old (founded 1950) corrosion monitoring and management specialist headquartered in Santa Fe Springs, California, and operating as a wholly-owned subsidiary of Halma plc, a UK-listed conglomerate of life-saving technology companies. The company is exclusively dedicated to corrosion management, offering a complete product and service portfolio built around three core sensing modalities: Electrical Resistance (ER) probes under the Corrosometer brand, Linear Polarization Resistance (LPR) probes under the Corrater brand, and Microcor high-sensitivity probes; the portfolio also includes ultrasonic non-intrusive monitors (Echo Point), real-time airborne corrosion sensors (AirIQ), access systems (fittings, SafeGuard service valves, retrievers, hot tap kits), transmitters and data loggers (wired and WirelessHART7), the Integrated Corrosion Monitoring System (ICMS), the Downhole Corrosion Monitoring System (DCMS), and supporting software (Data Offline, Data Online, Device Length Calculator, SAFR web register). End-to-end professional services span corrosion program development, installation and commissioning, preventative maintenance, access-under-pressure operations, and data acquisition and analysis.

Cosasco generates revenue through three streams: hardware sales of probes, transmitters, data loggers, access systems, and instruments; software licensing for Data Offline (one-time activation key) and Data Online (bundled with ICMS/IIU systems); and professional services delivered by in-house field personnel. Pricing is quote-based with no public list pricing, structured around multi-year enterprise contracts and sold via a direct enterprise field sales motion supported by owned offices in the US (Santa Fe Springs HQ, Houston), UK (Aberdeen), UAE (Sharjah as Middle East hub), Singapore (APAC hub), and China (Beijing), augmented by 40+ authorized independent representatives in 110+ countries.

The customer base is concentrated in oil and gas across the upstream, midstream, downstream, and gas transmission value chain, with secondary exposure to pulp and paper and specialty applications including wastewater, ultrapure water, and data center environments. End customers include supermajor oil and gas operators, and the company cites more than one million installed monitoring locations globally, underscoring both the scale of its installed base and the regulatory-critical, high-hazard-environment contexts in which its products operate.

Revenue model

1. Corrosion Monitoring Hardware Products: Cosasco generates revenue primarily through the sale of corrosion monitoring hardware including ER probes, LPR probes, corrosion coupons, transmitters, data loggers, service valves, access fittings, retrievers, and specialized instruments. Products are sold directly and through a global network of distributors.
2. Software Licenses and Activation Keys: Revenue generated from software licenses including Cosasco Data Offline Software and Data Online software. Data Offline requires a one-time activation key purchase. Data Online requires a separate license purchase sold along with ICMS or IIU systems only.
3. Professional Services: Comprehensive service offerings including Corrosion Program Development, Preventative Maintenance, Installation & Commissioning, Access Under Pressure services, Data Acquisition & Analysis, and SAFR Web Application. Services provided by in-house experts located globally.
