  • Take the guesswork out of gas detection by setting custom, actionable alarms for up to five of the following gases: LEL (Methane), LEL (Pentane), Cl2, CO, H2S, HCN, NO2, NH3, O2, PH3, SO2, VOCs
  • See all your people in one place with flexible, automatic connectivity to iNet Now live monitoring via cellular, wi-fi, or satellite
  • Share real-time gas readings, man-down, and panic alarms between peers, so the entire team knows who is in danger and why
  • Improve asset management by programmatically assigning monitors to your team, so you know who had the monitor when it went into alarm or when it went missing
  • Reduce human error with clear instructions (EVACUATE) when an instrument goes into alarm
  • Reduce the risk and cost of having different devices in the field by using one multi-purpose gas monitor across your site for everything from personal monitoring to confined space entry
  • Endure the harshest conditions thanks to an IP68 rating backed by a Guaranteed for Life™ Warranty
