Wenner Four-Probe Surface Resistivity Meter

温纳四电极表面电阻率仪

Many agencies now use surface resistivity as a quick durability check in place of slower charge-passed tests. This Wenner meter has fixed 38 mm probe spacing and reads 1–1000 kΩ·cm at 0.1 kΩ·cm resolution with ±2% accuracy. Geometry corrections for 100 × 200 mm and 150 × 300 mm cylinders are built in, and one charge lasts about 50 h.
