I have 3 Tilts and find them accurate. I love not having to take a gravity sample. Also being a bottler, having the temperature record and recording the historical high temp for each batch has really helped me dial in my carbonation levels.

I haven’t a clue how to get all the info out of my tilt… BUT… To monitor my brews with my phone and it appears quite accurate, its very nice…

Hello everybody. I just sanitized my Tilt 2 and threw it into my Grainfather fermenter with glycol chiller attached. The current temp in my Grainfather is 64 degrees but when i pull up the Tilt 2 to read the SG and temperature, it reads 74 degrees. Isn’t the Tilt supposed to read the temp accurately? The app says pre-calibrated temp and SG which i know i never pre-calibrated anything. Should i be worried or how should i fix it? Thanks.
Hard to say from here. My Tilts are accurate but it could be yours isn’t. Or your Grainfather isn’t accurate. It takes a while you adjust to the temp are they still both radically different?
I once went to buy a digital indoor/outdoor thermometer at Radio Shack. There were a dozen different models in the display case next to the register and no two of them had the same temperature being read and there was a 10 degree difference between the lowest and the highest. So silly.

See what the temp is now… Ifn you’ve 5 gallons of liquid… And you just racked to the fermenter… There is going to be 2 different temps… Be patient… Chime in tomorrow…

Thank you both for your input. Guess i was a little impatient on getting accurate readings right away from the Tilt. It is hitting spot on now for both temperature and SG. Being the first time i used, I didn’t know what to expect.

Just tested my new Tilt out in a glass of water. SG reads 1.0000, temperature reads 6616 deg F. I can calibrate it to 82 (read off my thermopen), just wanted to make sure this was normal? Sorry to Necro such an old thread.

There are alot of things to tinker with… with the Tilt… Almost all of it I don’t understand… BUT… I do verify gravity and temp just before I toss it in and close up the fermenter… To me, that is all that I need it to tell me… Its fun to check it out each morning…

I went through the “what thermometer is correct” thing with my brew system. The mash tun has a dial thermometer and a thermowell with a probe for the PID controller that turns on the sparge water pump. They never agreed with each other. So I stirred the mash and got out my traceable lollipop thermometer like this https://www.amazon.com/Thomas-Traceable-Shockproof-Waterproof-Thermometer/dp/B006OCN3PC/ref=sr_1_4?crid=1D47XLCKE76MW&keywords=Traceable+Lollipop™+Waterproof+Thermometer&qid=1641732351&sprefix=traceable+lollipop+waterproof+thermometer+%2Caps%2C187&sr=8-4
That one I trust is correct. Turned out the simple dial thermometer was correct.
My dial thermo is a Blichmann… it is adjustable… When reading the cooler temps, its quite accurate… for some reason, the upper temps arent… My thermapen claims its traceable… so that becomes the standard I compare too…

Got an email response from Tilt, they say it didn’t properly complete calibration, so they will be replacing it. Guess it wasn’t normal after all.

DAMN… shiny new gizmo… failed. I’m glad they stood behind their product…

So, I dropped my new replacement tilt in my carboy last night, was so excited I forgot to sanitize it 
, ah well. Then I was trying to figure out how to get access to the google sheets link and realized while at work I had forgotten to switch that feature on. So once I got home, I got it all set up and now have access to my fancy sheet. I am nerding out. 
My hydrometer read 10 points higher than the tilt is reading but I didn’t calibrate it beyond testing it initially in a tub of water. I’ll go through and calibrate it before next brew and see if it makes a difference.

I have 2 of them (had three but gave one to a friend) they have been very consistent but I’ve never but them all in the same fermenter to see their differences.
I believe you should test all yer equipment at least once a year… Didn’t Damien have a write up about this? I know, this hobby doesn’t need to be as scientific as possible… but trying to be accurate counts…
