Highly recommend the ‘Silver Well’ & a TDS/PPM Meter to accurately measure PPM of your batch.
This set-up is so easy & has all the functions required to make a quality batch of CS.

Link is for the Aust site but they do source their product from an American supplier Coyote Zenterprizes & rewire for Aust standards. I’m sure you can source in the USA directly from original supplier. The Home page of link has some great background info regardless of logistics, & helpful tips.

Measuring tool - I use the “Com 100' combined EC (Electrical Conductivity), PWT, TDS/PPM, & Temperature Meter” to measure every batch I make. It’s a very useful tool when making your own batches to give you an indication of PPM prior, & after batch completed.

I hope you get started soon now you know it’s much easier than we ever thought.

Wishing you great success with your home-made Colloidal Silver, and may it bring you much joy & great health benefits 🙏
