Measuring oxygen in vacuum furnace

vacuum furnace can be tricky in monitoring oxygen level. at systechillinois - we have solution to draw sample from almost no positive pressure environment (vacuum furnace). the pump we use, the sampleing technique we use. and the unique gas plumbing technique for particular application. make a different. oxygen in trace range can be an oxygen mixed with other background. when mixing in low positive pressure environment (vacuum furnace). this can cause interference with other oxygen cell typically in combustible background or hydrogen background. with systechillinois cell, this interference component to oxygen cell can be eliminated.Each vacuum furnace has it own configuration.
