GrayWolf Sensing Solutions

- Model II - Advanced Environmental Probes



For 20 years, GrayWolf has been transforming the way that environmental measurements are taken. And now we have acted on the feedback from our many worldwide IAQ, HVAC, IH and Green Building customers to introduce a range of very smart probes with highly advanced features.

  • Up to eight (8) sensors per probe.
  • Sensors are plug-and-play, easily swapped by the user. Calibration and other info is stored on each sensor.
  • 25+ available sensors; TVOCs, CO2, %RH, ºC/ºF, CO, O3, NO2, NH3, O2, H2S, NO, SO2, Cl2, HCN, HF, HCl, H2, ClO2 and many other parameters.
  • Connect to GrayWolf AdvancedSense meters or to Windows tablets/laptops via cable or via Bluetooth wireless (included as standard); your choice.
  • Connect one probe, two... up to four probes to platforms simultaneously.
  • Connect to remote devices via GrayWolfLiveTM and internal WiFi.
  • Internal fan increases sensor response and eliminates sensor generated heat.
  • Rechargeable (or powered via meter/ tablet). Charging cradle also operates as a wall-mount bracket or stand.
  • Alternatively mount on included mini-tripod.
