This product leverages the fluorescence method to track dissolved oxygen levels, offering several advantages over traditional electrode-based techniques. It provides precise and consistent monitoring data, exhibits robust resistance to environmental disturbances, ensures rapid measurement times, and boasts an extended operational lifespan. Moreover, the fluorescent film employed in this sensor has shattered foreign monopolies by being a domestically developed hard fluorescent film, which is resistant to scratching and unlikely to peel off.

1. Response time (T90): refers to the product's ability to achieve 90% of the accuracy of the measurement value within the specified time.
(1) Avoid exposing the sensor membrane head to the sun during storage.
(2) Avoid applying any mechanical stress (pressure, scratches, etc.) directly to the fluorescent membrane during use.
(3) Do not touch the fluorescent membrane directly with your hands, and do not scratch it with hard objects such as nails.
(4) It is recommended to replace the fluorescent cap of the sensor every 2 to 3 years.
(5) Check the sensor housing regularly for damage due to corrosion or other reasons.
(6) After a period of use, the probe may be contaminated by algae and needs to be cleaned regularly. Use a damp, soft cloth or a sponge with water to gently wipe the front fluorescent membrane. For some stubborn dirt, add some household detergent to the water for cleaning.
(7) When not in use, please place the front end of the sensor in a protective cover with a damp sponge to keep the sensor moist for a long time so that the probe can still be in good condition when it is used next time.
(8) If the sensor is in a dry state for a long time, the measurement results will drift, resulting in inaccurate measurement data. If it is in a dry state, it needs to be soaked in water for more than 24-48 hours before continuing to work.
