I wanted to get two nicer thermometers for my chargrill smoker, but have not found anything I like locally yet, so may have to order some. as a stop gap to get a better temp readings than with the stock thermometer, I bought a $5 meat thermometer at Wally world. It has a 12 inch long probe on it and registers from 50 to 650 degrees. I grilled a hole and mounted it about 3 inches above the grill on the left side of the grill. I calibrated it with boiling before doing this. Can I consider this fairly accurate as a stop gap for now?
