Overview

Gasboard-2500 is a TDLAS methane sensor with full-temperature pre-calibration for long-term stability in hazardous, humid environments, measuring 0-100% LEL (customizable to 0-100% vol) with T90 <25 s, low power and a modular design for process monitoring and pipeline security.

Key Features

  • 0~100% LEL measurement range (customizable 0~100%vol)
  • Super high accuracy over full temperature range
  • Fast response T90<25s
  • Super stable performance at high humility environment
  • TDLAS technique drive high methane selectivity
  • Low power consumption
  • modularized design for ease integration
