Benefits of the Sefram 9862 for the Measurement of Air Flow/Velocity in Ducts

  • Measures air flow or air velocity in ducts; with telescopic probe.
  • Additional measurement of temperature and relative humidity.
  • Ideal device for HVAC system performance analysis.

Sefram 9862 Hot Wire Anemometer

The Sefram 9862 is a hot wire anemometer that measures air flow or air velocity in ducts. Moreover the Sefram 9862 will give you additional information such as temperature and humidity. The hot wire technology enables high accuracy measurements. The anemometer can be used for the analysis of HVAC system performance. The telescopic probe makes the device very easy to handle.

  • Air velocity measurement: m/s, km/h, ft/min, miles/h.
  • Temperature measurement: °C/°F.
  • Humidity measurement: % rel. humidity.
  • Air flow measurement: m³/min or ft³/min.
  • Large LCD with backlight.
  • Min/Max/Avg and 2/3 Vmax function.
  • Fast response.
  • Telescopic probe.
  • Application:
    Measuring air flow or air velocity in ducts.
    Measuring the temperature and humidity.
    HVAC system performance analysis.

How Does the Sefram 9862 Work?

The hot wire is constantly heated up (above ambient temperature) and cooled by air flow. The hot wire temperature is sustained continuously. The hot wire current is linear to the flow velocity.
