Gas density indicator - GDI-100 - WIKA Canada. Gas density is a crucial operating parameter for high-voltage switchgear. If the required gas density is not present, safe operation of the plant cannot be guaranteed. With WIKA gas density measuring instruments, changes of gas volumes can be determined reliably (e.g. leakages).
