thermometer with K type thermocouple

[Gra]

Hi All

I was at Jaycar the other day to pick up some food safe grease and found this small thermometer with K type thermocouple. I had a DMM in a mobile phone holder on the side to monitor the boiler temp but this is much easier on the eyes. It also has high and low alarms as well, the thermocouple fits neatly in with the thermostat probe on my Vibiemme Domobar.


Cheers Gra…

Nice one Gra although I think your boiler is running a little cool.


Seriously good, simple mod!

Thats neat. How much did it set you back?

Looks like a good one for lots of coffee stuff It will save me having the big multimeter on the bench.

The only way it could be any better would be if it had a timer built in like I have seen a couple of American sites have had.

Thats excellent Gra - a variation on the Gronk (Slivia mod). What sort of temps have you been noticing?

It would be good to see how that compares to group head temp.

Hi Flynn

The machine sits on 108* - 109*after warm up I do a quick 2 second flush Lock and pull the shot I have not checked the temp @ the group because what has been ending up in the cup is great,What I dont know won’t hurt me at the moment. I then purge the steam the temp rises to 130*+ in no time I start steaming milk after 2 bar boiler pressure. Then steam off hot water on prime boiler and the temp drops back 108* 109*ready to go again.
Cheers Gra

Thats the one that I have but it only goes from 50* to 150*C and has high and low alarms.....Price $39.00..They do make another model that is -50* to 300*...Cheers Gra..

Hi Gra,

Does it have the normal TC connector to the display or is it hard wired to the display?

Re: thermometer with K type thermocouple

I bought one of these on Friday and installed it as per Gras. Very easy, but not sure about the best place to run the cable. I ran mine up through the temp. adjustment access hole and out under the lid. I wonder what sort of temp the plastic insulation on the wire can stand. I tied it to the shielded hose that runs to the OPV to try to keep it from touching the copper tubing

Ive been using it today (after buying a new battery) and noticing the temperature ranges between about 103º (after boiler refill) and 134º (steam temp) with around 110 - 111º idle.

Just revisiting this one again. I found a local source of a similar Thermometer with  a built in timer. Not cheap at $62 + postage. One source is http://www.hlpcontrols.com.au/prod04.htm Just the thing for manual brewer nuts like me

Good one Steve, I ended up using heat shrink over the lead to protect it from hot piping and run my lead out through the bottom right hand side.....
