Fluorescent cap daily storage
Put it in a protective cover with a moist sponge when not in use, so that the sensor stays wet for a long time. If the head of the sensor's fluorescent cap is dry for a long time, it will cause drift of the measurement result, so it needs to be immersed in water for 48 hours before continuing to work.
Notes:
1) Avoid exposing the inner surface of the fluorescent cap to sunlight.
2) Do not touch the fluorescent film with your hands.
3) Avoid any direct application of mechanical stress (pressure, scratches, etc.) to the fluorescent film during use.
