Thermocouple On special @ Jaycar

Re: Thermocouple On special @ Jaycar

Hey Gronk, I exchanged my broken QM1320 at lunch today. Easy, no questions asked. Hopefully the new 1320 will last until Santa comes and brings something more robust that I can also log roast data with.  

I spoke to the store manager on the phone today and he sounded a little unsure as to whether he would/could exchange mine.
I told him it was a 200km round trip and I needed a bit more reassurance before I wasted my time/petrol.

If I get there and he decides not to exchange it Ill just retire it to crappy multimeter duties in the shed, and buy a different model  

QM1602

KK, I picked up one of these from Jaycar the other day - it will do the trick whilst i wait for a the new CS USB DMM to hit the streets!

Digitech QM1320
Frequency DMM   on special $22.46

Thats the one Ive got. Mine reads 90 degrees in boiling water which is about 10% out.
I dont know how far it is out at roast temps though, but Ive decided to take it back to Jaycar and exchange it for something better.. and hopefully more accurate.

If you do a "Search" of the Forum using the keywords roast monitor youll turn up a wealth of information mate,

Cheers,

Re: Thermocouple On special @ Jaycar

Sorry to throw this off topic but I have become interested in home roasting - why do I need a thermocouple?? This is in relation to a popper method.

...they are also 50% more expensive!
It might work with the CS software but you should buy at your own risk.

The link that you have given is to a BM202 which Altronics is advertising as Q1080. The Q1080 is the Jaycar model number and they might be the same meter in a different case (I do suspect that Altronics is cashing-in on the fact that Jaycar dont have them).

http://www.altronics.com.au/index.asp?area=item&id=Q1080

Jaycar no longer carry them and Altronics is way over priced.

As mentioned the meter that we are testing with the software should be $80-$90 with USB (well depending on the US$-AU$ at the time). Still a fair bit cheaper and we have it working with a new revision of the CS software.... we just need to iron some quirks with the factory before we commit to buying a pile of them.

Re: Thermocouple On special @ Jaycar

These have been around for a while KK but I dont know if the data stream is compatible with the CS Roasting Software. Id wait to see what Andy works out with the one hes experimenting with,

Re: Thermocouple On special @ Jaycar

I looked up some older posts
And found this thermocouple that Mal recomended

Model Q1080 is a USB thermocouple with its own computer software $140.00

Re: Thermocouple On special @ Jaycar


KK, have a look at Intellidepths excel-ent spreadsheet.
http://coffeesnobs.com.au/YaBB.pl?num=1214989367


It was made for the CS software output but you could fudge it to graph using manual time and temp data pretty easily.

Not sure if this is what you are after, but you could play with this.

Re: Thermocouple On special @ Jaycar

I had to go to Jaycar to exchange a set of cables

I could not resist I got the Model QM-1323
Same as the one in post #1
But an updated model for $31.46

I will upgrade to the new one when it becomes available

Now I need a printable manual graph to record the results
Anyone have one on hand
