Ion Science CUB


The Ion Science CUB is a direct-reading instrument (DRI) that provides real-time volatile organic compounds (VOC) measurements, is wearable (badge) and includes optional alarm signals when exposure exceeds preset limits. The CUB units are being evaluated/tested as part of the Vapor Monitoring and Detection Project’s pilot-scale testing. The units will be used to provide real-time on-the-person indication of tank farm chemical vapors. The units will also be compared to other selected wearable DRIs. The CUB data will not be available to the plant software (TFMCS, OPSI/PI, or SAFER Systems) in real time but will be available to the plant software once the data is stored for evaluation. However, the recorded data may be considered as part of a broader vapor-program evaluation.
