The service life of analytical sensors directly impacts monitoring system operating costs and data reliability. Proper use and maintenance can significantly extend sensor life.
Electrochemical Sensors
Avoid prolonged exposure to extreme pH environments; replace electrolyte regularly; store in storage solution when not in use; avoid mechanical shock and vibration.
Optical Sensors
Keep the optical window clean; avoid exposing the fluorescent film/coating to strong light; prevent oily substance adhesion; regularly wipe the window with a soft cloth.
General Recommendations
Follow manufacturer-recommended cleaning methods; calibrate regularly with standard solutions; avoid rapid temperature changes; track response time and slope changes as aging indicators; establish a preventive replacement schedule.
