Hello,

 

The manual for the Gravity analog pH meter at:

 https://wiki.dfrobot.com/Gravity__Analog_pH_Sensor_Meter_Kit_V2_SKU_SEN0161-V2

says you need to immerse it in “3NKCL” solution for 8 hours before use.

 

What is this solution and where can I buy it?

Hi! The cap of the probe contains protective solution (3.3mol/L KCL).
