well I don't know how good that Tenergy unit is. Might be fine. I have a Protek 625 Due which I like a lot. It seems to measure IR while doing charaging but it was North of $200. I know the ichargers measure IR as seperate function. I have both an i106 and an I306B. But they don't come with power supplies so you would at least need to run them from a 3S lipo. You might consider one of the ISDT chargers likes this one:

It measures IR. I have this older model which is still available and also measure IR

I run it either with a small 12V Lead Acid battery I have or an old 6S 4000 i had laying around. I mostly use it to charge smaller batteries like RX batteries I have in my gliders. So for a little more, you can have a nice second charger that will also measure IR. You can of course connect it to a bigger battery or DC power supply and run it at full capacity.
