Gasurveyor 3-500

Key Product Features

  • Simple 2-button operation
  • Gas/air purge mode
  • Integral pump with flow-path protected by water filter
  • Can be calibrated via an IR link to GMI Auto Test Calibration Unit

The Gasurveyor 3-500 compliments the Gascoseeker with a similar performance, measuring % LEL and % volume flammable hydrocarbons, with the addition of the following features:

  • Automated zero during start-up
  • Gas/air purge mode
  • Optional rechargeable batteries
  • Optional gas alarm.

The two-button operation means the Gasurveyor 3-500 is easy to use and operator training can be conducted quickly. The rugged design enables the Gasurveyor 3-500 to be used in harsh environments. The Gasurveyor 3-500 is also fully compatible with our range of calibration software and equipment.
