How Awesome are Conductivity Meters?

Spoiler: they’re pretty awesome. There are a couple of common methods to determining water conductivity. One involves a relatively tedious step-by-step process with a handheld conductivity meter for a reading from a specific sample port in a DI water system at a specific time. Okay, yes I know I’m exaggerating a bit by characterizing it as tedious. But it’s a spot check process rather than a continuous one that involves human interface with a correct procedure followed. It is tedious and downright archaic when compared to the alternative.

And that alternative is to make a small investment in a panel or wall mounted continuous conductivity/resistivity monitor. This second option is superior in countless ways: it’s continuous, automatic, and can be multi-channel, meaning continuous monitoring of potentially more than one spot in a DI water system. There is one observation I’ve made with these. They can last for many years, but not forever. If the display stops working or works partially, it might be time to consider replacing the monitor. It can be awesome to go from one channel to two with today’s monitors. Not only that, but automated reports over time aren’t bad to have access to either.
