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.
