I need to purchase data logger

I like and use the 34970A. It's quite a bit cheaper as well if you don't need network and USB connectivity, especially if you're willing to buy used on Ebay.

If I had to log something I would use a Raspberry Pi with an AD or whatever on the GPIO. cannot beat the price.

ike it? Anybody using other unit worth commenting on?

Ok, thanks. I like the USB port and while I am conscience of the (bosses) m oney I spend on test gear, I think the other features are worth the added c ost. This unit will be used a lot and not sit on a shelf somewhere collect ing dust. I expect that I will need to buy a module to record 10 channels of temperature. If you could comment on that I would appreciate. I'm a bi t reluctant to have a sales person advise me on that and like to get the da ta from more than one source.

I have no idea what you said.

I can still do that with a Raspberry Pi to SDcard, to ethernet, or to WiFi with some small added electronics, as this is a design group that would be the way to go. Any idiot can buy anything or have it made. I would add my thermocouple interface with an USB to RS232 connector to the Raspi. or several, or design a 20 channel, WHAT temperature sensors seems a good question to ask too. I have a car thermometer you can record with a webcam, it all depends. Numbers I want numbers.

With a good webcam you can log a LOT of mechanical temperature sensors, EUREKA. In color too.

Would a lab jack work for you?

Not the fastest, but if you don't need the speed, the maybe it's OK.

I heard about those from Joerg, and I'm a fan. I've bought a couple of the U6 Pros which work great. The Visual C++ bindings work painlessly as well--dunno about their proprietary software.

I'm in Jan's camp when it comes to software--command line and lots of it. ;)

Yup, I use them in their RS-232 previous incarnation. I haven't tried the usb version. But Joerg's recommendation is good enough for me.

Hmm that reminds me of a very basic C question. (I'll ask on SEB.)

Oh, okay, it the bosses money. Understood. :) You'll err... he'll pay about $1K more.

34901A plug-in should work fine for that. I don't know if the DMM comes standard on the 34972A, but you'll need it to read the thermocouples. On the 34970A, option 001 is delete DMM module.
