Temperature measurements with K-type thermocouple probes (to which I alluded in a previous entry: Hardwired auto-off sucks. Don’t build it into tools/instruments you design.) are useful, but you’ll only get readings at the precise locations where you place the probe tips. There may be other spots in the apparatus under test where the temperature is anomalously high or low but you’ll never know it.

Thus, I decided to acquire some thermal cameras. My ultra-mini home workshop’s tool inventory now includes a FLIR ONE Pro (Android-compatible version with a resolution [in pixels] of 160 × 120) and two UNI-T thermal imagers: the UTi220k (resolution [in pixels]: 200×150) and the UTi260B (resolution [in pixels]: 256×192).
