ppm Gasurveyor 500 气体检测仪
PPM Gasurveyor 500同Gascoseeker 2-500具有类似的性能，测量％LEL和易燃碳氢化合物％的体积，但随着ppm范围的泄漏检测的各个方面增加。每百万元（ppm）的范围内具有高灵敏度提高了部分具有较高的灵敏度和更快的响应ppm的搜索范围。
In accordance with the Gascoseeker-500, the ppm Gasurveyor-500 has the following additional features: automated zero during start-up, manually selectable ppm and search ranges.
The ppm Gasurveyor-500 is easy to use, with operator training being conducted quickly and it is also fully compatible with our range of calibration software and equipment.
性能：
- Fast response search mode to locate ppm level leaks very quickly
- Automatic hydrocarbon range selection for LEL and Vol %
- Manual selection of ppm and search mode
- Simple 2-button operation, allowing user access to all features
- Automatic zero
- Audio/visual Geiger function (ticker) for leak detection
- Hydrocarbon resolution to equivalent of 5 ppm methane
