I doubt the 121GW will be UEI's choice for an automotive meter. UEI already makes an automotive meter that has better features for the Automotive job. They have a whole line of meter just for automotive. UEI already beats Brymen hands down in specific automotive testing and diagnostics tools and lab scopes.
The automotive one seem to have more features for recording individual cylinders, RPM’s, higher temp readings to 1,370C, Dwell, fuel injector testing timing pulse width, and of corse duty cycle.

http://www.ueitest.com/productsI recall Dave even mentioning that UEI already had a Bluetooth stack and protocol designed that they offered to use with the 121GW, so this tells me they already had a Bluetooth meter. I don’t know why Dave decided to make his own apps when UEI already had all this to start with? UEI already has an andriod and applemios app. The app looks basic but can do a 100ms refresh rate, record, graph, export to CSV, PNG, or JPG, continuous readings.

Brymen seems to do more handheld DMM’s, some clamps but none for a specific fast or job, eletricla tester, and some insulation test meter to 1kV. But I don’t see them doing any HVAC, gas detection sensors, combustion sensors, specific HVAC, or some other specific tool that UEI make. They have 2 automotive meters, but not any automotive lab scopes that also read ODBII codes,gas and leak detectors/gas anylizers, CO detectors. UEI seems to have more automotive selfie tools, not just an automotive meter.
I see these companies being on two different scales currently. Brymen has a lot of different specific clamps for electricians, general purpose DMM’s, only w automotive meter a no specific automotive testing tools or scopes, 2 insulation tester meter, no HVAC specific stuff. Brymen seems more on the electrician side of things with a few basic automotive meters, and UEI seems more into specific test equipment for different jobs and just happens to cover electric with the clamps as well.
