PPM Gasurveyor Options

The GMI 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.

The PPM Gasurveyor is a two button instrument designed to measure Parts Per Million, Lower Explosive Level and Volume flammable gas. The instrument is designed to the latest standards and is certified for use in Hazardous Areas.

The PPM Gasurveyor 500 contains the following ranges:

LEL, 0 to 100%.
Volume gas, 0 to 100%.
PPM Flammable.
Search mode (enhanced ppm flammable range).


Search mode is an enhanced variant of the ppm flammable range with increased resolution and faster response. Search mode can be used for detecting leaks which can then be classified using the more accurate ppm, LEL and Volume Gas ranges.


Fast Response Search Mode, to locate PPM level leaks very quickly.
Fully autoranging between PPM - LEL - Volume Gas.
Simple 2-button operation, allowing user access to all features.
Audible and Visual Geiger (Ticker) in Search and PPM.
Integral pump.
Optional alkaline cells or rechargeable battery pack.
Rugged carbon loaded polypropylene case, sealed to IP54 rating and suitable for outdoor use.
LCD with backlighting which displays the current gas readings (in both digital and analogue format).
Directly interfaces with GMI Auto Test Calibration Units.
ATEX approved.
