There are a lot of different factors that can affect the accuracy of a meat thermometer, but in general, Taylor meat thermometers are pretty accurate. One thing that can affect accuracy is where the sensor is located in the probe - if it's not in the center, it can give an inaccurate reading. Another thing to keep in mind is that meat continues to cook even after you've taken it off the heat, so you should always take your readings a few minutes before you think the meat will be done cooking. With these things in mind, Taylor thermometers are usually accurate to within a few degrees.
