Normally I wouldn't tout someone's product, but I think that this is quite useful and a bargain to boot.
I just used mine to measure the difference in the A/C evaporator temps in the 330 (yes the A/C now works!) and was impressed at what it did.
I got mine on eBay for $21.45 (buy it now price) including shipping:

and other than buying one from the seller, I have no vested interest.
