To help you achieve this goal, we have introduced Sieman’s high temperature resistant optical dissolved oxygen sensor — FC Optical DO Sensor. This innovative product is designed for processes such as steam sterilization, high temperature sterilization and cleaning (CIP), ensuring stable and reliable operation under harsh conditions.
Our optical dissolved oxygen sensors not only have a self-diagnostic function to detect and report the status of the sensor in time to improve the reliability and stability of the production process, but also use an electrolyte-free design to avoid the impact of electrolyte changes on the measurement accuracy. In addition, our sensors require no polarization time to respond quickly and perform dissolved oxygen measurements, increasing production efficiency.
The easily replaceable optical oxygen cap design facilitates maintenance and reduces line downtime. Choosing Sieman’s products means choosing a higher supply chain security and a better input-benefit ratio. We are committed to providing customers with stable and reliable biological culture solutions to help you accelerate scientific progress and product to market. Let’s work together to explore the future of biological culture!
