The ThermoWorks RT610B has good accuracy, good water resistance but only fair response times. It cannot be left in the oven/grill while cooking.
Don’t confuse this thermometer with its almost identically named RT610B-12 or -24. They have different feature sets! This unit has a shorter probe and slower response times. It DOES have an auto-shutoff feature, but does NOT have min/max or hold buttons. It does have good resistance to water incursion. The display is large and easy to read.
The manufacturer’s contact info, including telephone number and website, is found on the instruction sheet. There is no explicit warranty stated, however, this company stands behind its products.
We’re not recommending this thermometer as an instant-read. It lacks several features that its big brother has and is considerably slower to respond. The probe diameter is larger than we’d like to see. Just a few too many suitability-to-task issues…
