I did not read the description well ( it only reads in Celsius).  I purchased this for brewing beer.  To test the accuracy I checked the temp of boiling water and it was reading 92 C.  THat is 8 degrees off.  At freezing it reads 1.5 C which is close enough.  It seems to be at least 2-4 degrees off any other temp gauge that I have.
