Gasurveyor 11-500气体检测仪
The Gasurveyor 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。
The Gasurveyor 11-500 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.
In accordance with the Gasurveyor 3-500, the 11-500 also has the following features: automated zero during start-up, manually selectable purge mode, optional rechargeable batteries and option of gas alarms (not recommended if using as a purge instrument).
The two-button operation means the Gasurveyor 11-500 is easy to use and operator training can be conducted quickly. The rugged design allows the Gasurveyor 6-500 to be used in harsh environments. The Gasurveyor 6-500 is also fully compatible with our range of calibration software and equipment.
