Multifunctional Anemometer, Thermohygrometer, Luxmeter, and Brightness Meter TKA-PKM (61) for Accurate Environmental Measurements

The instrument is designed for measuring both photometric parameters and basic microclimate parameters: illuminance in the visible spectrum (380 ÷ 760) nm, energy illuminance in the spectrum (280 ÷ 400) nm - UV-(A+B), air velocity, air temperature and relative air humidity.Measurement range of illuminance 10 ÷ 200 000 lux Limits of permissible basic relative error of illuminance measurements in the visible region of the spectrum (380 ÷ 760) nm ± 8.0 % Luminance measurement range 10 ÷ 200 000 cd/m² Limits of permissible basic relative error of brightness measurements ± 10.0 % Air temperature measuring range -30 ÷ +60 °C Limits of permissible basic absolute error of temperature measurements in the range from +15 to +25 °? ± 0.2 °? Range of air velocity measurements 0.1 ÷ 20 m/s.
