Keysight (Agilent) B2985B Electrometer/High Resistance Meter
The Keysight B2985B Electrometer/High Resistance Meter is the world's only graphical electrometer that allows you to confidently measures small currents with 0.01 fA (0.01 x 10-15 A) resolution and large resistances of up to 10 PΩ (10 x 1015 Ω). It possesses a 4.3 " color LCD with a graphical user interface that provides trend chart and histogram data in addition to numeric information. These front-panel capabilities enable you to capture transient behavior and to perform quick statistical analyses without a PC.
Temperature and humidity are critical parameters for high resistance measurements. The Keysight B2985B electrometers contain both temperature and humidity sensor interfaces, and a dedicated thermocouple (N1423A) is furnished with these models. The EE07 Digital Humidity/Temperature Probe from E+E Electronik can be used for humidity and temperature sensing, which provides more accurate temperature data than a thermocouple. Even when operating in AC mode with 0.1 PLC integration time, the B2985B's advanced design provides cur measurement performance that is much better than conventional picoammeters and electrometers.
Specifications for the Keysight (Agilent) B2985B Electrometer/High Resistance Meter Include:
| Measurement resolution | 6.5 Digits |
| Cur measurement | 0.01 fA - 20 mA |
| Minimum range | 2 pA |
| Resistance measurement | Up to 10 P? |
