Digital thermometers can be found that are also NIST-traceable, meaning their absolute, not only relative values are accurate. Cooper makes their NIST-traceable DPS300, -58deg to +302deg F, or in Centigrade if you like, for about $35. The Cooper DPS300 cannot be fully immersed, just the sensor stem which is about 5" long and made of stainless steel. It has some more rather neat features.
Your Kodak thermometer broke mounted in the metal support? I consider my Kodak thermometer to be my most durable because of the protective support.
