Could this price be right? for this: http://webtronics.stores.yahoo.net/fluk54dualin.html
(I know NOTHING about thermocouples and Meters, but going from what was said here, this is the one to have?)

If so... I will DEF order one?

I bought this item from them in Dec. of 2005, for $296 and change.

They shipped it immediately, and as I said previously, included the free gift of a set of pliers. Make sure you follow the directions on the home page about ordering the "free gift" in order to get it because if you don't order the gift properly, you won't get it.

For day in, day out use subject to the rigors of the real world, nothing beats a Fluke.
For casual home use, an Omega HH506-RA or Extech 421509 will be more than adequate.

They are less than half the money of a comparably featured Fluke and include rudimentary logging software that imports directly into Excel.

Accuracy is very good and consistent.

I recently tested boiling and freezing points with distilled water. Two Extech 421509 varied ±0.1°F between units and channels with the same thermocouple type K. Variation between thermocouple types K and T was also ±0.1°F. Measured temperatures within ±0.1°F.

Boiling point was calculated using http://terraserver-usa.com/ to determine local altitude, the 10 minute data from the weather station at the local college http://www.piercecollege.com/offices/we ... quinth.htm and http://www.csgnetwork.com/h2oboilcalc.html.

Yayyy!

Just ordered my fluke Thermocouple data logger thing :) the 54-II yesterday. I can't wait to get it and start measuring stuff :)

I already have Eric's Thermometer adapter installed on the anita, I have to contact him and see what I need to do to swap out the digial thermometer with a thermocouple? Then I can do those cool graphs of that gauge vs the scace :)

I love getting new gear.

Now the next question is do I get the Scace I or II. I want a pressure test device, but I could get a fluid fill gauge and build a PF myself with parts from hardware store (Like the one in this post) for pretty cheap?

Greg's thermofilter is used to regulate regional, national, and world barista competition equipment where portability and standard measurement are of paramount importance (i.e., if the competition rules say regulate to x bar, event leaders want to be certain it's the same everywhere, period). If you want to economize, using a stock pressure sensing portafilter, plugging a digital pressure gauge into Eric's E61 adapter, or building your own should satisfy your needs (no comment about the 'want' factor).

Just looking around for other units that could be comparable and I came across the Omega HH147 which looks identical to the Royston unit pictured above.

http://www.omega.com/ppt/pptsc.asp?ref=HH147

Interestingly enough, the Omega page claims a Resolution (accuracy) of 0.1°C/0.1F, 1°C/1°F, although, reading the spec sheet they actually say that it's 0.1% rdg not 0.05% rdg as per the Fluke and HH506RA.

The HH806AU is also spec'd to 0.05% rdg. The A variants of the HH806 also have double the save data and 16 times the logging data capacity.

Has anybody used the 806's yet?

cheers,
James

You're getting resolution and accuracy a little mixed up - time to burn some midnight oil with Google. :)

The 806AU had a software bug and needs Version 1.2 of the SW to communicate properly with the PC. One advantage to the 806AU is the AC adaptor and the software GUI is a little better but still not what it could easily be, given a little programming work.

Thanks Eric! :oops:

It's been a while since I've had to think about these things!
cheers,

Just to throw another thermocouple thermometer into the mix, I just aquired a Cole Parmer Digi-Sense model 91100-50. It sells for $295 on their site, is made in the USA. It's dual channel, logs up to 1000 readings and can output in comma-separated format over IR (has an optional IR-to-RS232 DB9 cable for PC interface).

Details, specs, and manual at:
http://www.coleparmer.com/catalog/produ ... ku=9110050

Anyone else used this unit?

Doesn't look to bad, the CSV output would be very nice. I still refuse to spend the money on the fluke software but every time I do some data logging I start thinking real hard about getting it. After you key in a few hundred data points it gets old fast.
