Probing the SR500
8675309
I was looking at my Redi-Check meat-therm-setup and behold the probes almost fit into the top of the chaff collector. A small drill bit to open it up a bit allowed the probe to work.!!!

I did some tests and found some interesting info on the Low-Med-High settings as far as temp goes.

Attached are results - the graph lists 1-2-3-4-5 at the bottom those represent 30 second intervals.
Bean was an El Salvador.

I ran on Low for 0-150 seconds
I ran on Med for 180-270 seconds
I kicked to high at 300 seconds to 450 seconds.

1C started outlier at 270 seconds and stayed with me up to 330 seconds where the temp
stayed at 442, dropping to 441 for a few seconds before kicking up again.
2C started at 450 second mark and I let 2C continue for 5-7 seconds before hitting cool.

The cool cycle dropped the temp to 133 where I dropped them onto a cookie sheet for further cooling.

As I am recovering from an emergency appendectomy I don't have a lot I can do other than sit around and turn dials on the SR500 - so I did another run, this time a Columbian.

The graph bottom line is 30 second intervals.

I did notice that 1C outlier came in at 400 but 2C started at the 450 mark.
Cool down stopped at 140 degrees.

There was a leveling off and very slight decline in temp during 1C as I saw with the El Salvador.

I hope you are feeling better. I am not too familiar with the SR500. The probe looks good and I think you should get good results with repeatable temperature measurements.

Thanks - and yea this is an exercise in discovering / monitoring temps on the SR500 - I was surprised at the 'range' in the Low-Med-High modes of the machine and I hope this helps others (and myself) in their roasting processes.
