Topic: Need Digital Temp. Gauge (not dig. therm.) (6 msgs / 86 lines)
1) From: ROASTAMAN
Hello,
It's time to determine the water temp.coming from my brew head on my Isomac espresso machine.  Does anyone know where I can get a digital temp. gauge, (not the typical digital thermomoeter) that can measure the water temp exiting my brew head.  David Schomer shows one on his web site but I am not sure what they cost or where to get one.  Any suggestions?

You should take a look at the Fluke website for reference, I seem to recall
Schomer had a Fluke meter. BTW, expect to pay in 200+ range.http://www.fluke.com/products/sections.asp?AGID=5&SIDjohn

The thermometer that David Schomer uses is the Fluke 50.  It is a thermocouple
thermometer.  It is accurate to 0.1degree.  They can be found on many web sites
for around $120.  Just search for thermocouple themometers.

You probably mean repeatable to 0.1 degree. Accuracy is a whole 'nother 
matter.

And temperature distribution is changing over time and across position...
I think 0.1 degree reading is unnecessary.
For frugal home roasters with some very basic engineering skills, I
recommend to buy bare thermocouples ($5-20 a piece for scientific
grade) and a cheap digital volt meter. It's easy to make a table/graph
for voltage to temp conversion.
If several people are interested I'll write some more about it some time.
(but I should finish my roast chart project first)
