Krohn-Hite

Krohn-Hite Corporation is an American manufacturer of precision laboratory instruments, founded in 1949 and headquartered in Brockton, Massachusetts. The company specializes in tunable active filters, precision calibration sources, and phase measurement instruments used in research, production testing, and metrology environments. Krohn-Hite is particularly recognized for its wideband and variable-frequency active filters, which provide accurate signal conditioning with selectable filter types and cutoff frequencies.

The company's calibrators and phasemeters serve calibration laboratories and production test environments requiring high-accuracy DC and AC signal sourcing. Krohn-Hite instruments are designed to meet the demands of engineers who require repeatable, low-distortion signal conditioning for sensitive measurements.
