SDG #317 ET12S 2 in 1 Thermal Camera and Multimeter Combo, Bside A2

Two budget test meters are examined here, and they sit at opposite ends of the feature scale. The Bside A2 is a genuinely pocketable auto ranging multimeter with non-contact voltage detection, aimed at people who want something small enough to live in a tool bag rather than a full bench instrument. The review looks at how it handles basic DC and AC voltage, resistance and continuity, how quickly the auto ranging settles, and whether the NCV function is sensitive enough to be trusted for live mains checks or is prone to false triggers from stray fields. Build quality, probe quality and lead sockets receive attention as well, since those are usually the first corners cut on a meter this cheap.

The ET12S is the more interesting proposition: a handheld multimeter with a low resolution thermal imaging sensor built into the same body. The value question with combination devices like this is whether the IR camera is a usable diagnostic aid or merely a novelty overlay. The review examines the sensor resolution and refresh behaviour, palette and temperature readout options, how well the thermal image resolves small SMD components and hot spots on a PCB, and how the imaging side compares with the dedicated thermal cameras already covered on the channel.

For anyone repairing electronics, the conclusion concerns expectations. A cheap integrated thermal sensor can find a shorted part or an overheating regulator, but pixel count and thermal accuracy limits matter, and the meter half still needs to be trustworthy for the combination to make sense over buying two separate tools.
