GMI Gasurveyor 11-500 LEL VOL CO (CGI/CSM)

This instrument is supplied with alkaline batteries. For the rechargeable battery version, please select the Gasurveyor 11-500R from the OPTIONS dropdown. The Gasurveyor 11-500 is a two button instrument designed to measure Lower Explosive Level, Volume flammable gas and Oxygen. 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 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. It 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. The Gasurveyor 11-500 contains the following ranges: LEL, 0 to 100%, Volume gas, 0 to 100%, Oxygen, 0 to 25%. 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 two-button operation means that it is easy to use and operator training can be conducted quickly. FEATURES Automatic hydrocarbon range selection. Two operating modes: Combustible Gas Indicator (CGI) mode and Confined Space Monitor (CSM) mode. Automatic datalogging in CSM mode and Manual datalogging in both CGI and CSM modes. Manual selection of purge mode. Simple 2-button operation, allowing user access to all features. Automatic zero. Gas/air and gas/nitrogen/air purge mode. Hydrocarbon resolution to equivalent of 50 ppm methane. Accurate, robust and extremely reliable instrument. Integral pump with flow-path protected by water filter. Rugged carbon loaded polypropylene case, sealed to IP54 rating and suitable for outdoor use. 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).
