Does anyone have a DI meter built into their RO/DI?

[gregzz4]

I should have elaborated on my setup
I have both a single and a dual meter
I measure supply water, post RO and post DI
FYI, I also have pressure guages on my supply and pre-RO to monitor the filters. You could say I'm a bit OCD

For the OP, as Brad stated, if it's included and is comparable to what I linked above, go for it

I only mentioned what I use as I like to keep an eye on most stages of my system
