G90 Portable Gas Detection Alarm

Configure G90 for the leak-search or multi-gas monitoring task instead of choosing one fixed detection setup.

  • Choose a suitable sampling mode

    The source lists diffusion and pumped probe versions as well as a pumped multi-gas configuration; select the version for the actual measurement task.

  • Investigate different leak scenarios

    Probe, methane triple-range and optional remote-laser configurations address different inspection distances and concentration ranges.

  • Keep the team connected

    The listed Wi-Fi, Bluetooth and optional 4G/GPS functions support data sharing when included in the ordered version.

G90 has distinct versions; confirm the exact sampling method, sensors, range and optional laser module.
