Cygnus 1 Ex PRO Ultrasonic Thickness Gauge (UTG) is designed for taking reliable ultrasonic thickness measurements (UTM) in all hazardous gas Zones (0, 1, 2), coal mines and combustible dust Zones (21, 22).
  • This anniversary kit includes Cygnus 1 Ex PRO gauge, a Cygnus T5B-Ex Probe and a FREE Cygnus S2C-Ex Probe*
  • *Only valid when ordering through Cygnus Instruments Ltd

The Cygnus 1 Ex PRO Anniversary kit includes a Cygnus 1 Ex PRO Gauge, a Cygnus T5B-Ex Probe and a FREE Cygnus S2C-Ex Probe featuring: 3 measuring modes, Live A-Scan & B-Scan, advanced data-logging and manual gain and gates. This intrinsically safe instrument requires NO plant shutdown, NO Hot Work Permits and NO need to remove coatings! It is certified safe for use in Zone 0 Explosive Atmospheres – making it ideal for corrosion monitoring in fuel depots, road and vessel tankers, mines, chemical plants, oil and gas, refineries, pipelines, hazardous storage tanks and other hazardous environments. It is also certified safe for use in combustible dust Zones (21, 22), such as flour mills, sugar plants, and wood manufacturing.
Key Features:

  • Certified to ATEX, IECEx, UKEX for use in all hazardous gas Zones (0, 1, 2), coal mines and combustible dust Zones (21, 22)
  • Intrinsic Safety protection – No need for hot work permits
  • Continuous measurement on hot assets in-service, using the NEW Cygnus High Temperature Ex Probe
