The model 291 is a portable, battery-operated survey instrument for evaluating the resistive properties of static control products such as static dissipative packaging, flooring, or work surfaces over the range of 10E3 to 10E12 ohms or ohms per square.

The model 291 uses a parallel electrode configuration conforming to ASTM D-257. It also accepts external electrodes for point-to-point and resistance-to-ground measurements. A test lead is included for resistance-to-ground measurements. Model 291 is convenient and easy to use. Simply place the 291 directly on the item to be measured. An easy-to-read, color-coded LED decade display quickly and clearly indicates the resistivity or resistance range.
