About this product
The TOOLTOP ET14C is a handheld thermal imager aimed at homeowners, electricians, and maintenance tinkerers who need to see heat instead of guessing at it: hot breakers, overheated connections, heat-leaking insulation, or underfloor heating coverage. The headline specs are a 240x240 infrared sensor (as noted in the listing's ISR240x240 designation), a 25Hz refresh rate that keeps the image fluid while panning, and a 2.8-inch display with an included stand for hands-free work. In this price band, IR resolution and refresh rate are exactly the two specs that separate useful tools from toys, and both are strong here. At around $192.69 (55% off), with 938 recent sales and a 96.1% positive rating, it is a credible entry into serious home thermography — just confirm the temperature measurement range matches your intended use before ordering.
