My oven thermometers have become coated with a thick layer of soot and grease as to be completely unreadable. I thought I would give a digital oven thermometer a try. I selected the Maverick OT-03 Oven Thermometer over several others. Here is a link to a good description of the Maverick OT-03.

Maverick OT-03 Oven thermometer

One thing I like about it is that it is rated up to around 572 degrees. Most of the others are only rated to about
350-400 degrees. I have used several other digital meat thermometers and have ruined several probes until
I realized why the probes were failing after a few uses. One is that the most of the probes are not
designed for high temperatures and exposure to temperature above there rating will ruin them.

The Maverick OT-03 is rated to 572 degrees is one of the highest temp range for a low cost digital
thermometer. Another brand that cost over $70 is rated up to 700 degrees.

One difference between a digital oven thermometer and a meat thermometer is the higher temp display.
Most of the meat thermometer only provides readout to about 200 degrees.

The Maverick will provide alarm setting that will alert you if the temp is 15 degree above or below your setting.

Also the Maverick is not an instant read thermometer, but provides an avg oven temp over the cooking
cycle. the avg is reset when the temp drops below a minimum range.

I have used it twice now for low and slow bbqing. Once with a Boston Butt for pulled pork last week, and
a Texas-style brisket yesterday. Both were done over a 10-12 hr period.
The main advantages of using the digital oven thermometer are:

1) temp reading at the level of the meat being BBQ-ed.
2) Not have to open the hood to take a reading
3) faster reading of temp change compare to the hood thermometer

Note; a small change in the setting of one of the burner knobs can make a large change in the grilling temp.

The Maverick is designed with a clip to attach to the rack. From experience with using digital meat
thermometers, I found that the probe wire will short out when exposed to high heat for any length of time.
Also do not allow too much moisture or get the probe wire wet. It will cause the enameled coating on the
wire to corrode, which is turn will short out the wires.

To help prolong the life of the probes, I now cover the wire leads with aluminum foil to reduce the
exposure to high heat. Also because I do the cooking over a 12 hr period. At night, the dew or fog can
leave a lot of moisture on exposed surfaces. I keep the read-out unit in a towel to protect it from
moisture. Also just wipe the probe to clean, DO NOT SOAK the Probe or get the wire wet, It will cause
the coating of the wire to corrode.

I did think about drilling a hole in the back of the
stationary hood, and attached the probe there. But I believe just clipping it to the warming rack where I
smoke/slow cook the meat works a lot better.

Here are some photos of how I used the unit.

to protect from moisture.
