Gas density monitor - GDM-100-CV - WIKA Canada gas density, for high-voltage switchgear, is a critical operating parameter. If the requiredgas density is not present, safe operation of the switchgear cannot be guaranteed. The gas density measuring instruments from WIKA warn reliably against dangerously low gas quantities, even under extreme environmental conditions.[email protected]
