I just smoked a batch of SS this past wk end. Used a MES-40 with PID. Worked very well Also had 2 maverick meat probes and the pid air probe. 6 hrs into smoke I inserted the meat probes in 2 different tubes and they both went instantly to 149. It then took 3 1/2 hrs to get one to 158 and the other to 153. Had pid set at 175. Isn't this a long time to gain 4-6 degrees. I checked probes the day before in boiling water. Checked ok.
