Forbes Marshall offers a comprehensive, high-performance portfolio of dissolved oxygen (DO) sensors and analysers engineered to deliver precise, real-time oxygen measurement across the most demanding industrial environments.
From measuring extreme low-trace levels (ppb) to high saturation (ppm), our robust sensing solutions guarantee process efficiency, environmental compliance, and reduced operational downtime.
Our advanced lineup leans heavily on cutting-edge optical measurement technology (luminescence quenching). This drastically simplifies operations by entirely eliminating the need for delicate membranes, chemical consumables, and messy electrolytes.
To suit specialized industrial needs, the portfolio also boasts advanced capabilities, including industry-first ATEX/IECEx certifications for explosive environments, fully autoclavable and sterilizable designs for hygienic applications, and built-in digital interfaces like Bluetooth, HART, and RS485 Modbus for seamless control system integration.
