POLI

Advanced Multi-Gas Detector

The WatchGas POLI in pumped version is an advanced instrument with an integrated pump that enables a full range of sensors for a variety of applications, including confined space entry. The POLI in diffuse detection version is a multigas detector that is ideally suited for worker safety monitoring in hazardous locations.

Smart sensors contain calibration and ID information, so you can change them on the spot. This makes the POLI is the ideal device for an emergency response to incidents involving hazmat response. The construction of the POLI is very robust and the operation is intuitive with two buttons and a large LCD screen. The man-down alarm function, which is unique in this segment of the market, warns nearby personnel when the user has stopped moving.

  • Available in diffusion- or pumped version;
  • Man Down Alarm with real-time remote wireless notification;
  • IP-65 (pumped versions) and IP-67 (diffusion versions);
  • With water and dust resistant case;
  • Real-time gas concentration readings and alarm status enabled by state-of-the-art wireless technology;
  • Large graphical display icon-driven user interface through intuitive, simple-to-operate two-button user interface;
  • Easy access to pump, sensor, filter, and battery;
  • Over 30 interchangeable sensor options, including PID for VOC, NDIR and catalytic for combustibles, and NDIR for CO2;
  • Intelligent sensors store calibration data, so they can be swapped in the field.
