The PPM Gasurveyor 500 compliments the Gascoseeker 2-500 with a similar performance, measuring % LEL and % volume flammable hydrocarbons, but with the addition of ppm ranges for all aspects of leak detection. The high sensitivity parts per million (ppm) range is enhanced by the ppm search range with higher sensitivity and faster response.

In accordance with the Gascoseeker 2-500, the PPM Gasurveyor 500 has the following additional features:

  • Automated zero during start-up
  • Manually selectable ppm and search ranges
