What is the exact NaOH solution to fill inside the membrane cap of DO Sensor(SKU:SEN0237-A ) ?
I already read the wiki https://wiki.dfrobot.com/Gravity__Analo ... KU_SEN0237 but I'am confused about " Only by adding the NaOH solution into the probe can it be ready for use." what it the exact solution is it 50%,60%,80% or 100% NaOH to fill inside the membrane cap? can anyone help me
