This is pretty much the only thermometer I've used for the past 30 years. I have a Kodak process thermometer and the Patterson ones always agree with it. Be aware that it only goes up to 30C so if you are doing colour you'll need one that goes higher. Definitely recommend this thermometer.
A Precision tool, been around for years. A pleasure to work with.
