Product description

CJZ7J(A) Laser Gas Drainage Comprehensive Parameter Tester (referred as the tester hereinafter) is a new generation of multi-functional and portable device which can upload information in real-time. It integrated the latest laser gas analysis technology, rapid sampling technology and location reporting technology to meet the needs of periodic measurement during drilling and drainage.

Feature

  • It adopts the laser detection technology to measure the methane concentration quickly and accurately; it has rich functions, and can simultaneously measure up to 10 parameters
  • The sampling interface is flexible and suitable for single hole sampling and draft tube sampling
  • The tester has localization function of devices (for use with the corresponding system)
  • Measurement data can be uploaded wirelessly in real time (for use with the corresponding system)
  • With flexible operation mode, it can be used alone or with an optional intelligent terminal
  • It is suitable for both single hole measurement and gas drainage pipeline measurement
