Inexpensive Digital Strip Chart Recorder - Too_Many_Tools - 2006-01-10 20:07:00

I am looking for an inexpensive digital strip chart recorder.

Does something like this exist?

Are there addons for a laptop, pda or pocket pc that allows one to
record, store and display analog data similar to the good old chart
recorder?

Thanks for any leads.

Inexpensive and "strip chart recorder" are mutually exclusive.

Yes, there are lots of addons, google gets tons of hits 
"http://www.google.com/search?hl=en&q=analog+data+recorders"

The next question is: "how much do you want to spend ?? "

Portable, USB, serial, .... lots of questions.

What are you trying to measure will determine what kind of analog data 
recorder to buy.

I would agree...I am surprised that in today's world of electronics
that an inexpensive turnkey appliance is not available.

The uses for something like this is many....and I am not trying to be
specific since this will be used to measure a number of physical
parameters.

Let's say one wants a digital solution to what a old HP 680 Strip Chart
Recorder would work for...is there anything out there today that works
the same?

Radio Shack used to sell a Metex VOM (Metex ME-11) that had a serial port 
output and software that made essentially a data logger which you could then 
pop into an excel or Quattro spreadsheet and massage the data anyway you 
liked. I bought two of them from their on-line catalog when they were on 
sale maybe 3 years ago, suspect you can still find them, maybe with an USB 
port these days. I use one of mine for metering the transmitted signal from 
NAA to detect SIDS. Lots more practical than my old Rustrak strip chart 
recorder, I can just throw away the "uninteresting" data and not use any 
paper at all. The other one is just a backup for my Fluke 77.

I don't know if the software is available, separately, but for $25 you 
can buy a 4 channel analog digitizer that comes with such software.

Something like the USB-1208LS from Measurement Computing (I'd post a
link but their referral/tag/cookie system seems to want two or three
lines for the URL) plus an old laptop PC might do the trick.

It's a relatively inexpensive USB gadget that comes with basic "strip
chart" software as a demo app. They have other, faster, and more
expensive models and more software, of course. IIRC, they still include
their Universal Library w/ the device, so you can write your own apps
with your own look & feel.

Higher end stuff is available from places like http://www.astro-med.com/
... and priced accordingly. Good gear, though.

OK,

So the spec's are: not battery operated and must weight in at about 15 
pounds.  ;-)

I have used some of the smaller devices at : 
http://www.dataq.com/c_cr/index.htm

There will be trade offs on "chart speed" = sample rate and resolution 
(step size) and max input voltage.

good luck

Sure

Look For Data loggers.

DataQ makes some cheap ones www.DataQ.com

http://www.picotech.com/ do a number of devices that may be suitable.
