Painter AS840 Digital Ultrasonic Thickness Gauge: Ultrasonic thickness measurement
For metalworkers and inspectors who need precise thickness measurements on-site, like checking pipeline integrity in the field or verifying material specs in a fabrication shop. This isn't just a tool for safety compliance; it's your reliable partner for ensuring project accuracy without second-guessing.
The gauge's auto zero calibration means you get a stable reading on uneven surfaces, so you can trust the 0.1mm resolution when assessing weld quality. With sound velocity measurement, you adjust for different metals quickly, avoiding costly errors in mixed-material environments. The backlit LCD stays clear in low-light workshops, and data storage lets you log measurements without fumbling for notes.
Powered by AAA batteries, it's lightweight and ready for long shifts, with auto power-off to conserve energy. Use it to streamline your workflow and deliver confident results every time.
