The ThermoWorks RT600B is an accurate thermometer that is splash-resistant, but its response time is too slow to be used as an instant-read tool. It cannot be left in the oven/grill while cooking.
There are two virtually identical units from ThermoWorks: the RT600B and the RT600C. Don’t confuse them! The B unit is relatively slow to respond, but has a wider temperature range. The C unit is very quick with a temperature range more suited to food measurement.
This unit, the B version, will NOT shut itself off – you must remember to do it or the batteries will run down. It has a min/max feature and can be switched between F and C scales. The packaging claims that it is dishwasher safe to 190ºF – an unusual feature.
The manufacturer’s contact info, including telephone number, e-mail and website, is found on the instruction sheet. There is no explicit warranty stated, although the packaging gives a number to call if warranty service is needed. This company stands behind its products.
The fairly slow response time precludes a strong recommendation, but the water resistance and wide range work in its favor. Our focus is food measurement, so we’ll give it a Bronze medal for overall quality and performance
