Thermohygrometer with TNS-index calculation "TKA-PKM"(24)

The instrument is designed to measure indoor relative humidity, air temperature and temperature inside the black ball, as well as to display the parameters calculated in real time: TNS and WBGT indices (°C), wet-bulb temperature (tvl, °C), dew point (ttr, °C), average radiation temperature (trad.cf., °C), thermal irradiation flux density (W/m2). The range of temperature measurement inside the black ball is extended up to +100°C. The function of setting by the operator of the exposure time during the measurement of thermal indices and parameters, in the range from 5 to 60 min, with a discreteness of 5 min, was introduced. The whole process of measurement of thermal and WBGT indices is fully automated. Additional functions of processing the received information are introduced: memorisation, averaging, selection of minimum and maximum values, graphical display of measured and calculated microclimate parameters.
