are grilling/BBQ Temperature probes compatible among different grilling thermometers?
Not necessarily Chad. I know for certain my Thermoworks & ThermoPro probes were not compatible with my Mav-732, & vice-versa. (I don't have the Mav any more).
The jack-plugs on both the TW & TP are too short for the Mav jack-plug socket, & the Mav jack-plug is too long for the TW & TP jack-plug sockets.
(If memory serves me right, the jack-plug on the Mav was also slightly thinner as well as being longer. Maybe it was a 2.5mm jack-plug as opposed to the 3.5mm on the TW & TP)?
The TW (DOT/Smoke) & my TP (TP-20) jack-plugs are compatible.....I've just tried it. Both worked perfectly with each other.
The TW Pro-Series probes imo are the best quality for what we use them for. They have a chamfered barrel that would go through the grommet a bit easier with a little bit of lubrication on it. (Hold the grommet on the back side as you push it through).
Edit:
All of the 3 jack-plugs, mentioned above, are of a 2-pole type. I don't think temp probe jack-plugs are of a 3-pole or 4-pole type, but I could be wrong.
Generally 3-pole & 4-pole 3.5mm jack-plugs are used for things like headphones, (left-channel, right-channel, microphone (if applicable) & ground), & other small consumer electronics.
The less common 2.5mm jack-plug, (which I think was on my Mav probe), is used in specific devices like some older cell phones and communication equipment. While not as prevalent as the 3.5mm jack-plug, the 2.5mm jack-plug serves its purpose in more niche applications or where space is a concern.
Apologies for the long-winded reply.
