The Keysight B2985B and B2987B Electrometer/High Resistance Meters streamline the characterization of surface and volume resistivity in insulating materials by providing accurate resistance or current versus time information in real-time through their front panels.
You can measure a material’s surface or volume resistivity in film or sheet formats using the Keysight N1424 Resistivity Cell fixture and custom resistivity measurement fixtures for other sample forms or shapes.
Additionally, they provide an unmatched current measurement resolution of 10 aA (0.01 fA) and a built-in 1000 V voltage source that allows you to measure resistances of up to 10 PΩ (1016 Ω)
Insulation and surface resistance are typically measured 60 seconds after applying a test voltage (electrification) as per the ASTM D257 standard (unless otherwise specified), so it is important to be able to measure these parameters over time.
