Main Features：
1. Oxygen dissolved sensor is a highly stability sensor, no need to change breathable film and electrolyte. Please avoid contacting sharp instrument in case of broken the film.
2. Please put bumpers on it while carry out or at the process of storage. The way to cover or take down the bumper is clockwise rotate slowly, please avoid pressure or yank forcibly.
3. If the sensor accumulated lime scale, you can soak the sensor with 10% diluted hydrochloric acid about 3 minutes, and then rinse with clear water. If the sensor is contaminated with organic pollutant, you can soak the sensor with 80% ethanol about 10 minutes, and then rinse with clear water. The maintenance will not affect the normal use.
