SST Sensing's OXY-Flex oxygen analyzer is suitable for measuring in oxygen closed systems, such as ventilation pipes and boiler exhaust flues.

The OXY-Flex oxygen analyzer is designed to measure the oxygen concentration in air or gas mixtures with temperatures of -100°C to +400°C. The oxygen analyzer employs a well proven, small zirconium dioxide-based element at its heart and due to its innovative design, does not require a reference gas. The oxygen sensor element is mounted in the tip of the stainless-steel probe and is protected by a sintered stainless-steel cap. The IP65 waterproof die-cast aluminum housing accommodates the electronics and provides the interface to which the customer can connect.

The OXY-Flex oxygen analyzer uses a unique closed-loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures.

The OXY-Flex can be configured to output measuring ranges of 0% O₂ to 25% O₂ or 0 % O₂ to 100% O₂. The entire measurement range is linear in both cases. The outputs can be configured to either 4 mA to 20 mA and 0 V_DC to 10 V_DC outputs or an RS-232 serial communications interface.
