Hi, my name is Linges. I have a question about the DO (Dissolved Oxygen) sensor. I want to measure the oxygen level in a shrimp tank. Do I need to use the membrane cap, or can I avoid it? Should I fill the cap with NaOH solution before placing the sensor in the tank?
Also, I’m confused about the calibration process. Why do we need to fill the membrane cap with NaOH for calibration instead of just placing the sensor directly into the water?

Hi, I have a question. Does the DFRobot sensor usually take a long time to get a stable reading? I’ve tried using it in my shrimp larvae tank, and it takes about 1–2 hours to stabilize. Can you please help me with this issue? Thank you.
