The GMI Gasurveyor 3-500 is a two button flammable gas leak location and purge instrument, designed to measure Lower Explosive Level (LEL) and Volume flammable gas. The instrument is designed to the latest standards and is certified for use in Hazardous Areas. The instrument contains electrochemical sensors with a life of 2 years.

The Gasurveyor 3-500 contains the following ranges: LEL, 0 to 100%, Volume gas, 0 to 100%. The LEL range indicates the explosibility of the flammable gas in the sample. This is displayed as a percentage of the lower explosive limit (LEL) of the gas. For methane 100% LEL corresponds to 5% Volume methane in Air.

The LCD display shows the current gas readings in both analogueand digital form together with operational and statusinformation. The display is protected by a toughened glasscover. Backlighting is provided to enable the display tobe seen under low ambient light conditions.
