Group,
I believe this is what we paid for our Agilent datalogger:
34970A Data aquisition/switch unit with Benchlink software £949 ($1518)
34901A 20 Channel mux module £290 ($465)
so a complete 60 channel thermocouple thermometer costs £1819 ($2910)!
Yes it does sound too good to be true but we have one and it is an excellent
piece of kit. As for whether there is anything negative to say, I can think of
only one thing. The connections are quite annoying (small screw terminals in
the module not plug in thermocouple connectors) .Then again you can imagine how
big the equipment would have to be to accomodate 60 thermocouple sockets, even
the miniature type.
Best thing is to get one on demo from Agilent. This is what we did and we were
very impressed. Other manufacturers equipment we had in on demo did not come
anywhere near the price or number of channels on the Agilent.
Regards,
Duncan.

This almost appears to be too good to be true. Let's see if I have this right.
34970A Data Acquisition/Switch Unit with software, $1290
34901A 20 Channel Mux, $395
34307A Thermocouple kit with 10 thermocouples, $98
Total for a 20 channel thermocouple system is $1881.
That's cheap! OK, what is wrong with this picture (if anything)? Anyone have
anything negative to say about this system?

We also use the 34970A for data acquisition with HP BenchLink for our safety
testing and are very pleased with it's performance and ease of use. We also
have a Hydra II system which mostly gathers dust now. The 34970 / BenchLink
system is so much easier to setup & use. Also the data log is a snap to link
into a Word report.
For what it's worth.

Richard,
We use an Agilent 34970A data aquisition unit with three 34901A 20 channel
mux modules fitted. This is not a PC card but a rack and stack instrument about
the size of a bench DVM that connects to the PC via a serial cable. It also
comes with the software. Very similar to the fluke hydra II.
This has proven to be an excellent instrument and well worth the investment.
Most other equipment of the same price could only offer around 10 channels of
measurement whereas this allows up to 60. It is also modular so you only need
buy as many 20 channel mux modules as you need.
Regards,
Duncan

I do any monitoring any temp testing with a Fluke Hydra II and
associated PC software. Set up and define probes, start software,
dump into an Excel spreadsheet or report. Communication between
the Fluke and the PC is done through serial ports. - Doug McKean
