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.
The device is designed to measure the speed of movement, temperature and relative humidity of indoor air with the ability to display information on a PC.
Ambient temperature
from -30 to +60 ° C
Relative air humidity at an ambient temperature of 25 ° С
up to 98%
Atmosphere pressure
80 ÷ 110 kPa
Sanitary and technical supervision in residential and industrial premises, museums, libraries, archives; certification of workplaces and other areas of activity. Anemometer + thermo-hygrometer can measure the temperature and humidity of the air flow, speed and volumetric flow both in the duct itself and at the entrance or exit from it. With a hot-wire anemometer, you can measure both at individual points and perform a series of measurements along the entire length of the canal. If you enter a surface area, the device will automatically calculate the volume of air flow in m 3 / h.
