  • Improved Wi-Fi hardware
  • Enhanced GrayWolfLive® (optional cloud service for remote data access) with faster data refresh times, calibration status/tracker and more
  • Barometric Pressure now included as standard
    • Accurate atmospheric pressure display/logging
    • Auto-compensates for pressure/altitude effects on mass concentration and moisture readings
    • Differential Pressure remains optional
  • USB-C socket for data output, software input
  • AS-201/2 exceptionally accurate hotwire airspeed probe connects via rugged push-pull socket at top
  • ALL WolfOS software updates, including feature enhancements, will be available on-line at no charge (no need to return to GrayWolf for firmware upgrades)
  • Spanish, French, Chinese, Arabic, Portuguese, and other languages will be available later in 2023
  • Battery life specs are improved
Download the preliminary AdvancedSense XM brochure, and/or request the updated version, when released, with enhanced specs and features.
