Specification :

Model 272A provides rapid, accurate, and repeatable measurements of surface resistivity, volume resistivity, or resistance to ground in one versatile instrument. Use it to measure the resistive properties of static control products such as static dissipative packaging, flooring, or work surfaces over the range of 8 x 10E3 to 2 x 10E13 ohms or 8 x 10E4 to 2 x 10E14 ohms per square.

Model 272A includes a concentric ring probe and support base conforming to ASTM D-257, ANSI/ESD STM11.11, and ANSI/ESD STM11.2 for making surface and volume resistivity measurements. An adaptor is included for resistance to ground measurements.
