• Intuitive: Provides clearly structured measurement menus for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts or at ventilation outlets
• Space-saving: Simply combine universal Bluetooth handle with 100 mm vane or hot wire probe head and extendable telescope (1.0 m)
• Convenient: Wireless probes, internal memory for data storage, and USB port for data export
• Versatile: the 440 dP is equipped with an integrated differential pressure sensor and can be expanded with a large range of digital probes
• 440 dP Air Velocity and IAQ Measuring Instrument with Differential Pressure Sensor:
• Includes integrated differential pressure sensor for checking filters, for Pitot tube measurement (sold separately) or K factor measurement
• Combines a compact design with intuitive measurement menus
  
• Compatible with wide selection of air velocity and IAQ probes (probes sold separately)
  
• Provides clearly structured measurement menus for carrying out measurements in ventilation ducts and at duct/ceiling outlets
  
• Volume flow is precisely calculated, due to convenient input of the size and geometry of the duct cross-section
  
• Displays timed and multi-point mean calculation, average volume flow, current reading and min/max values
  
• Additional practical measurement menus include determination of volume flow via differential pressure and K factor, long-term measurement, volume flow measurement with a funnel
  
• Internal memory stores up to 7500 measurement reports
  
• USB interface allows for easy data export and optional printout of measuring values
  
• Rear magnets securely attach instrument to metal surfaces, such as ducts
  
• Automatically detects connected probes
  
• Large, backlit color display
  

• Vane Probe (Ø 100 mm) with Bluetooth and Temperature Sensor:
• Measures air velocity, volume flow and air temperature at air/ceiling outlets
• Measuring range: 59.1 to 6890 fpm, -4° to 158 °F
• Universal handle easily connects to other probe heads or telescopes, resulting in wider range of applications and less equipment requirements
• Easily carry out measurements at air/ceiling outlets by fitting vane probe to extendable telescope with 90° angle
  
• Bluetooth handle makes it more convenient to carry out measurements and guarantees less cable clutter in the case
  
• Practical button on handle to store individual readings for multi-point mean calculations, or to start and stop measurement series for mean calculations over time
  
• Use vane probe in conjunction with testovent measurement funnels and flow straighteners (sold separately) to test incoming / outgoing air at plate outlets, ventilation grilles, and swirl outlets
  
• Intelligent calibration concept allows 440 Meter to be used continuously, since only individual probes need calibration
  

• Hot Wire Probe Head with Temperature/Humidity Sensor:
• Measures air velocity, volume flow, air temperature and humidity in ventilation ducts
• Accurate measurements from 0 to 9843 fpm, due to robust sensor and automatic absolute pressure compensation
• Air temperature and humidity measuring range: -4° to 158 °F, 5 to 95% RH
• Easily attaches to robust telescope (extends up to 39 in.) for convenient measurements in ventilation ducts
• Practical button on handle to store individual readings for multi-point mean calculation
• Intelligent calibration concept allows 440 Meter to be used continuously, since only individual probes need calibration
