Default Mash water temperature sensor with alarm

Let me start off with saying I am lazy.

It takes about 30 minutes to heat up 12 gallons of water to 166 degrees for mash in water. I want to start the burner and walk away until it reaches the correct temp. Does anyone know of a probe or sensor that has an alarm that will go off when the water temp hits what you want? Does this already exist?

All the alarms you want my friend!


Go to a restaurant supply store and see if they have any thermometers with alarms. Stick the probe in the water and set the alarm for about 3*F shy of your set point. Walk off...

The gas flames licking up the side of the kettle may burn through the sensor cable though...

stuff it between the top of the lid and the pot, put the rest of the cable and the sensor on top of the lid?

me? no! never! sorry, i'm just in love with my electric setup. i couldn't imagine walking away from a gas setup, especially an automated one. when my rig was propane i used to get nervous running into the house from the porch for hop additions or a bathroom break.

but i leave my eHLT going while i run errands all the time. i even sous vide in it unsupervised.

Yes! I am all the time running into town with my brew going. I usually go get ice just after I sparge. Granted, I live in the country and "in-town" is only a mile away... haha! I know what you mean though... I am even contemplating prepping my brewery for an after-work brew day and leaving the panel on. I will give my wife a call to ask her to flip the pumps and element-on switches about a half hour before I leave work. That should get me started with mashing as soon as I get home!

Ok, next question guys: Let me start off by saying I'm lazy. Is there any way to measure like the specific gravity of my beer-making liquid just before fermentation? Like a calibrated device that floats and reads the gravity?

:derp:
