ThermoWorks RT304 Water Resistant Thermometer Review

ThermoWorks RT304 Water Resistant Thermometer Review

The ThermoWorks RT304 Water Resistant Thermometer has good accuracy, fairly good response times and is immune to incidental moisture. It cannot be left in the oven/grill while cooking.

The unit has an on/off switch but it will NOT turn itself off automatically. There is a min/max button and another to change between F and C scales. It is sealed against moisture. The buttons and display are small and might pose a challenge for some users. Response times are better than many of its competitors, but not in the super-fast range.

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 give this thermometer a Bronze medal for accuracy, construction and performance. The lack of an auto-off feature or a hold feature, combined with the small buttons and display, prevent a higher rating.

2) Try to post your question to the appropriate page.

3) Tell us everything we need to know to help such as the type of cooker and thermometer. Dial thermometers are often off by as much as 50°F so if you are not using a good digital thermometer we probably can’t help you with time and temp questions. Please read this article about thermometers.

The Pit Barrel Cooker May Be Too Easy


The PBC has a rabid cult following for good reason. It is absolutely positively without a doubt the best bargain on a smoker in the world. Period. This baby will cook circles around the cheap offset sideways barrel smokers because temperature control is so much easier.

Our Favorite Backyard Smoker

The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing. At its crux is a patented firebox that burns logs above the cooking chamber and sucks heat and extremely clean blue smoke into the thermostat controlled oven. It is our favorite smoker, period.

Blackstone Rangetop Combo: Griddle And Deep Fryer In One


The flat top does the burgers and the fryer does the fries. Use the griddle for bacon, eggs, grilled cheese, and so much more. And why deep fry indoors when you can avoid the smell and mess by doing it outside!

Grilla Pellet Smoker proves good things come in small packages

We always liked Grilla. The small 31.5″ x 29.5″ footprint makes it ideal for use where BBQ space is limited, as on a condo patio.
