Copper Sulfate Crystals

Copper sulfate crystals are to be added to your portable reference cell when either setting up the cell or servicing it after use. Ensure you mix the copper sulfate crystals with either de-ionized water or Corrpro Copper Sulfate Anti-Freeze solution. Make sure that when adding the crystals that enough are added so your solution is saturated and crystals are visible in your cell's solution. 

When ordering the copper sulfate crystals, please indicate how many jars you would require and if you would need copper sulfate anti-freeze solution to complete your cell.
