Measure inductors, capacitors and resistors at DC or from 20 Hz to 300 kHz with BK Precision’s new 891 Bench LCR Meter. The 891 features a bin sorting function and frequency sweep function for fast and efficient grouping and characterization of components. Users can easily read vital parameters and measurements on the expansive 4.3” color display.
The 891 LCR Meter offers the most in user versatility with its compact 2U half-rack form factor allowing for the bench or rack mount installations. Even more, standard USB, GPIB and LAN interfaces augment productivity by enabling remote control abilities to carry out daily operations in an array of industries.
