These rugged, lightweight resistance testers are designed for measuring surface resistivity in ohms per square inch, displaying values through an LED screen with a number of color-coded ranges. Also applicable for testing resistance to the ground, these testers are convenient handheld units. Indicators warn the user of low battery levels or danger being present when a material is at the higher end of the dissipative range.
