The Oxy-Flex Oxygen Analyzer is suitable for measuring oxygen levels in closed systems such as ventilation pipes and boiler exhaust flues. It can measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400⁰C.

The oxygen sensor element is mounted in the tip of the stainless steel probe and is protected by a stainless steel cap. The IP65 waterproof die-cast aluminium housing accommodates the electronics and provides the interface for the customer to connect to.
