Benefits

An additional measurement channel (relative humidity) expands the operational capabilities of the hot-wire anemometer. High sensitivity. High reliability and non-criticality to the characteristics of controlled flows. Multifunctionality of the anemometer.
Equipping the USB interface allows you to: expand the capabilities of the device without prejudice to the time of information retrieval, abandon paper media while reading the microclimate parameters.
In the instrument settings menu Anemometer + Thermohygrometer “TKA-PKM” (60) you can:

  • enable / disable the automatic device shutdown,
  • select the unit of measurement for the volumetric flow rate (l / s or m 3 / h),
  • set the cross-sectional area of ​​the flow.
  • Nine data cells are organized in the memory of the device. One cell stores the values ​​of air velocity and volumetric flow rate, as well as time stamps to the stored data.
