Default thermometer issues

ok i recently decided to test my digital thermometer against a old standard meat thermomater i had laying around. I was getting a sample of my brew down to 60 to hydro and to my surprise the digital read 68 while the standard read 60. So i boiled some water to see while one was off and they both read 212 at the exact same time. Any ideas???

You should also calibrate with freezing water. A glass full of ice chips and water (that's been sitting for about 10 min) should do the trick.

After going through many thermometers and bad luck, ended up just getting this and not looking back. Pricey but worth it!! http://www.thermoworks.com/products/...thermapen.html

Yeah, I have several digital stick thermometers that I written the temp difference on with a sharpie. Some are over 5 degrees =/-. I ended up buying a digital stick thermo. with a calibration screw. Really made a difference. Was less than 20 bucks at Kitchen and Co.
