General Tools & Instruments’ PalmScope is a full-featured pocket-sized video inspection system built to survive the harsh environments of HVACR maintenance and plumbing. The system’s clamshell design allows the camera-tipped probe to be coiled safely and conveniently inside the device. It can be operated with one hand, leaving the other hand free to use tools. It has many plumbing applications, such as detecting leaks and cracks in ducts and piping, inspecting for corrosion and deposit buildup, and reading hidden part and serial numbers.
