Teledyne GMI Gasurveyor 11-500

The Teledyne GMI Gasurveyor 11-500 compliments both the Gascoseeker, Gasurveyor 3-500 and the Oxygas instruments with a similar performance, measuring % LEL and % volume flammable hydrocarbons, but with the addition of oxygen.

The Gasurveyor 11-500 is designed for either gas/air or gas/nitrogen/air purging, with the ability of the Gascoseeker and the addition to measure oxygen during a nitrogen purge.

In accordance with the Gasurveyor 3-500, the 11-500 also has the following features:

  • Automated zero during start-up
  • Manually selectable purge mode
  • Optional rechargeable batteries
  • Optional gas alarms (not recommended if using as a purge instrument)

The two-button operation means the Gasurveyor 11-500 is easy to use and operator training can be conducted quickly. The rugged design allows the Gasurveyor 6-500 to be used in harsh environments. The Gasurveyor 6-500 is also fully compatible with our range of calibration software and equipment.

Applications

  • Leak detection
  • Bar hole survey
  • Gas/air or gas nitrogen air purging
  • Gas escape detection
  • Petroleum installations
  • Hot work permitting
  • Confined space (only hydrocarbon and oxygen gases)
