PPM Gasurveyor 500同Gascoseeker 2-500具有類似的性能，測量％LEL和易燃碳氫化合物％的體積，但隨著ppm范圍的泄漏檢測的各個方面增加。每百萬元（ppm）的范圍內具有高靈敏度提高了部分具有較高的靈敏度和更快的響應ppm的搜索范圍。
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.
