USB Multimeter for Temp ??
Henry Kolesnik
mV/deg F....but I'm getting lazy...
I'd like to find a reasonably priced but accurate and durable multimeter
with a USB interface and software so I can log temp with some kind of
time stamp using my Fluke temp probe. If someone experience with any
I'd like to know what's available new and used. I'm attempting to
evaluate some insulation and thermal mass for a passive solar home
design.
tnx

Why tie up the multimeter..
This does not look bad:

But if you insist:

but the reviews aren't that great.
Lets see what others scare up..

Where you can install a computer, one could use 1-Wire devices
and software like 'digitemp' or roll-your-own.
For standalone, I have used educational data loggers like
the TI CBL and serial-port interfaced loggers from the likes
of DH, Vernier or Fourier, which for the more general purpose
models include a 200mv range.

Here's what $40 gets you, note the limited measurement range and sample
frequency:

I used a bunch of them to evaluate a Solar Air Heater I designed
(http://www.solarsponge.com), along with other passive cooling and
heating aspects of my home.
You can use as many as you want and actually get thermal mappings of a
space. i.e. suspend then at different heights in a room and get a map
of the temperature layers. I've put then in air ducts, in water, as
contact thermometers etc
Infinitely better than a PC and a multimeter.

I like the Microdaq unit. Good price, good value.
A couple cheaper units, pretty good prices:
http://www.weathershop.com/USB1_temperature_logger.htm. $59.95 USD. Includes
software, temperature range from -25 to +80°C. Logging intervals from 10 seconds
to 12 hours and capacity of more than 16,000 readings.
Omega has what appears to be the same unit as above, @$60 USD.

Omega has the OM-62, standalone. I've worked with one, stick it where you want, then download the data. Temp dew point and
RH.

it to the PC, it has an IR port which many laptops have..including desktops.
I own a 289, I like it. It can do up to 200 hours of recording
and data can be read back in a chart etc..

Check that out. It can computer link of show the data
on it's own VGA screen along with saving it for later
viewing.

The Themrochron iButtons are a much sexier solution. Only $25ea, have
up to a 10 year battery life, are waterproof, and are only the size a
few stacked coins.

Serial and USB readers are available, and data can be exported to
Excel etc.
You can get little plastic tags to attach them to to things too. I
hang one off my harness when I go canyoning, to log the water temp.

I believe the best to be as below:

These are cheap, simple, accurate enough, easy to use, and pretty much
perfect for your application. The previous generation of logger we used
(ACR) were about $800 per unit, and these do basically the same thing for
$30 a piece. Thank you China! It would be prudent to buy several, and put
them in different spots so you can also evaluate temperature variations.
I think it will save you time, and get you better and more useful data if
you go with this approach rather than trying to use a general purpose
multimeter.

DataWatch Elite M2000 temperature logger with LCD display and is RS232
but works with a conversion cable to USB. Come with software and can
store 1,868 samples, sampling at 1 to 255 minutes with a real-time
clock, -40F to +158F. Cost $45.00.. Replaceable lithium cell runs it
for a year. I have a PDF spec sheet if anyone wants it, let know.

Google can't find it, how about a link ?

not PCI? anyway, not my problem - do a search for "data collection cards"
you will find thngs like this www.superlogics.com/usb.asp

PCI is going away if not already completely gone on new PCs, USB will be
here for quite a while in some form. USB also allows you to easily move the
device from one PC to another, and connect it to laptops.

I think it's because more and more people are moving to laptops and USB,
IEEE-1394 and PC-Card's are the only ports available.

ask for one at www.global-sensors.com , they'll send you a PDF

Flukes.One of them is a Fluke Wavetek, it has a plug in thermister
wire.I just noticed when I turned it on, over to the left side it says,
bat.I reckon I ought to replace that battery.
