Temp Probe on MES 30

post #1 of 11
Thread Starter 

I thought that i would start a survey on how reliable the Probes are on the MES 30.

I Guess I could do the calibration but I thought someone might know. I thought about buying a Taylor Thermometer but I do not want to open the door to check since the probe was included with the unit. Also how many people use a wired thermometer? Maybe with the lead ran thru the vent.

Both the meat probe & the controller are usually not accurate. Most folks use a wired probe & either run it through the top vent or just shut the door on it. The rubber seal on the door won't damage the probe wires. You may want to look at the Maverick 732, It has dual probes, one for the food & one for the cabinet temp. It also has a wireless remote you can carry around with you so you don't have to stay by the smoker.

Also note that the temp sensor on the MES is monitoring/reporting the temperature along the back wall of the box. So even if the MES sensor is accurate/consistent for that location in the box, it is better to measure the temp nearer to the center, where the meat is located. That is another reason why many use a separate thermometer.

My last run I had a 8 degree difference between the MES meat probe and the Mav732 meat probe, But one was at each end of my Ribroast so that could account for some of the difference...JJ

I found it to be 5 degrees higher than it should be.

Is the difference a constant? 


I ask as one could mount a quality manual unit on a shelf , that could be read through the window, and then make mental adjustments to the data provided by the OEM equipment ..

The difference was measured at 225 degrees using an accurate(verified by bioling point testing) thermometer.

I also wonder about the accuracy of the factory sensors. I found a 13 degree difference in the meat probe to an external one I was using with the factory one being the higher of the two, but when the same external probe is just hanging through the vent to compare cabinet temps to the factory cabinet sensor, the factory one usually runs about 15 degrees cooler. I have also noticed large temp swings shortly after adding some wood chips. The control will not vary much at all, but the probe hanging will run up to into the 260's when the unti is set at 210-215 degrees. Anyone else notice this?

I know this is an old post but I am having the same issues as above. I have a ThermoPro 2 probe, the meat probe and the MES probe are within 5degrees of each other but the cabinet probe is about 20-30degrees higher than what the MES says. Where should i put the TP probe to get the most accurate temp?

Did you solve this? I'm seeing same thing with my TP08

No I have not solved this however I have just been going off of what the TP says
