Title: pH Meter Question
Post by: bast on January 14, 2018, 06:00:33 PM

What is the best manufacturer of pH meter for measuring pH of seawater (or saltwater)?

I prefer a lab-grade, high-accuracy pH meter.

Where I can buy it? Please show me the link.

The problem is not the ph_meter, because this is in easy words a high ohm voltmeter. The accuracy comes with the type of electrode.

look, companies like Methrom, Mettler Toledo Ingold and others.
