FermSense Optical Dissolved Oxygen Sensor

DynamicPE FermSense DO-O combines an optical sensor type PSt7 and electro-optical module in a single probe. With a maximum measurement range of 0–100% O₂ and a detection limit of 0.03% O₂ / 20 ppb, the wide range sensor is ideally suited for O₂ monitoring in the biotech sector. A trace range variant covers 0–5% O₂ or 0–2 mg/L with 0.5 ppb resolution. Probes connect directly to the control unit via RS-485 Modbus RTU and integrate easily at the measurement site through a standard PG13.5 stainless steel thread.
