STORING EC PEN IN PH SOLUTION??

I've got the bluelab combo meter its expensive but you get a full 5-year warranty and i bought it in a sale also don't be pinching your girl or parents toothbrush lol

Same here. Worth every penny. The only other thing I ever used was the cheap gh liquid test kit before I cud afford my meter and b4 my combo meter arrived. But I wouldnt use any other meter. Accuracy matters to me.

That begs the question of how you are to protect the pH component of a combo meter without damaging the EC component.

How do companies like Bluelab do it and offer a 5 year warranty? It could be that the Chinese company making these made a poor design choice in the material.

To the OP. D you know someone with a known working EC meter you can compare against to verify the EC probe is still working?

Na unfortunately i dont. Ill just use a seperate one i know is ok. Cheers
