Hi Bill,
I was going to suggest, depending upon Matts interests, that perhaps
he could use a PIC or ATMEL device with analog inputs and roll his
own.
Most PIC models have 10 bits but some do have 12 bit. You could use
an external A/D for 12 bits or more.
I actually used this for a
Does anyone have a good solution for monitoring 4-8 different voltages
at the same time? I only need a sample rate around 1-2 Hz, but would
need GPIB, serial, or ethernet support with protocol documentation.
Which end of the $$$ scale are you interested in? Are you willing to spend
cash to
Hi Chris,
That is an interesting item and the pricing is certainly on the inexpensive
side. Sparkfun has it for $30. Sure beats trying to make your own boards and
come up with the parts.
I have an old development system from mikroElektronika [

] for the PIC line. They

remote Temp monitoring needs.
They have other cool stuff too. Worth a look.

Thanks,

Very nice!
And at those prices, why bother to roll your own, unless you have some
truly unique need.
Thanks for the tip off.
Dave Baxter.

In place of the meters/scanner you could use the MI5010 multifunction interface

I can vouch for the 3421A -- nice, inexpensive box that is low power and
fairly painless to program. There are other

Be careful on buying scanners. The issue is not the scanner
but in the fact that they use plug in cards. Make sure you
get the type of interface card(s) you need. There are a lot
of HP/Agilent scanners out there minus all their cards.
Saying that you can anything from a 3421A to a rack size

Any help identifying a solution other than 8 voltmeters would be much

Hi Matt,
1.Is the voltage AC or DC ?
2.What is the voltage range ?
3.What kind of resolution ?
