Request InfoKeithley Instruments Inc.Keithley Instruments Inc. has introduced a picoammeter with dual ±30-V, independent, nonfloating bias sources and 1-fA measurement resolution. Model 6482 provides two independent picoammeter/source channels in a 2U, half-rack enclosure, allowing simultaneous measurements across both channels. Measurement accuracy is ±1% on the 2-nA range, and dynamic range is from 1 fA to 20 mA. The wide measurement range ensures high sensitivity and resolution for low-current applications that require making measurements at multiple points simultaneously. The 2-nA measurement range...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueExtended InGaAs DetectorsHermetically sealed, surface-mount device-packaged 1.7- and 2.6-μm InGaAs PIN ATLAS photodiodes from Marktech Optoelectronics Inc. are designed for spacecraft, aerospace, medical, defense,...Photonics.com 6/29/2023Compact UV LaserThe Spectra-Physics® Vanguard™ One™ UV125 from MKS Instruments Inc. is a compact UV laser designed for bio-instrumentation applications.
