Barben Receives Dual Seal Approval For Optical Oxygen Sensor From UL

CARSON CITY, NV – Barben Analytical announces that it has received dual seal classification for its BOS fiber optic oxygen sensor per ANSI/UL 12.27.01. BOS fiber optic sensors are used in conjunction with the Barben 4401 OXY oxygen analyzer for liquid and gas phase measurements.
