Thermo-hygrometer with THC-index calculation TKA-PKM (24) with verification is designed to measure indoor relative humidity, air temperature and temperature inside the black ball, as well as display the parameters calculated in real time:

• THC and WBGT-indices,
• wet bulb temperature,
• dew points,
• average radiation temperature,
• thermal radiation flux density.

The thermohygrometer is used for sanitary and technical supervision in residential and industrial premises, museums, libraries, archives; certification of workplaces and in other areas of activity.

• The thermohygrometer has a unique ability to determine the values ​​of THC and WBGT indices in real time due to the simultaneous measurement of air temperatures and inside the black ball, air humidity and the calculation of the exact values ​​of the temperature of the wet thermometer using a special program protected by the Certificate of official registration of the computer program No. 2004611468.
• According to the letter of the Chief Metrologist of the All-Russian Research Institute of Optical and Physical Measurements (VNIIOFI) V.P. Kuznetsov's "black sphere" is not a measuring instrument and its verification is not required. The parameters of the sphere must be verified during testing and manufacturing.
• Additional simultaneous determination of the values ​​of the average radiation temperature and the intensity of thermal radiation provides an effective and reliable assessment of possible thermal overheating when studying a hot environment.
• Equipping the device with a USB interface allows you to expand the capabilities of the device without compromising the time of taking information and refuse paper media when reading the microclimate parameters.
• The temperature measurement range inside the black ball is extended to +100°C. A function has been introduced to set the exposure time by the operator when measuring thermal indices and parameters, ranging from 5 to 60 minutes, with a resolution of 5 minutes. The whole process of measuring THC and WBGT indices is fully automated. Additional functions for processing the received information have been introduced: memorization, averaging, selection of minimum and maximum values, graphical display of measured and calculated microclimate parameters.
