• IR20 & IR20WS

    Research Grade Pyrgeometers

    IR20 is a research grade pyrgeometer suitable for high-accuracy longwave irradiance measurement in meteorological applications. Thanks to Hukseflux’  technological innovation, IR20 is offered at a significantly lower price level than competing models of the same performance level. IR20 is capable of measuring during both day and night. In absence of solar radiation, model IR20WS offers even better accuracy because of its wider spectral range.
    • Breakthrough pricing for a pyrgeometer
    • Correction of temperature dependence by use of the measurement function
    • High sensitivity
    • Fast response time (3 s)
    • On-board heater
  • TCOMSYS01 Hot Cube

    Thermal comfort measuring system - a new tool for research and education

    TCOMSYS01 is a measuring system to help understand and quantify “causes and effects” leading to human thermal comfort. The TCOM01 body is temperature stabilized at 33 °C so that it offers a relatively direct measurement of the human experience. In essence, TCOM01 is a miniature thermal mannequin, measuring according to the innovative Hot Cube method. The heater power required to keep the TCOM01 at a constant temperature is the main measurand. Incorporating 5 heat flux sensors with a black absorber also offers a detailed picture of the heat gain and loss from different directions, and a good indication of convective and radiative asymmetry. Other measurements are sensor body temperature, air temperature, and relative humidity. In its standard configuration, the system consists of an MCU (Measurement and Control Unit) and a TCOM01 sensor. The MCU offers a direct connection to any local area network and “Ethernet over USB”. TCOM01 is also available as a sensor only.

    TCOMSYS01 advantages

    • direct representation of the human body
    • helps understand and quantify the detailed physical cause and effect of thermal comfort
    • simple experiments can be used to quantify the sources of heat gain or loss
    • offers directional information
    • good addition to Wet-Bulb Globe temperature measurement
    • robust, student-proof
    • “stand-alone”; equipped with its own clock and memory
    • safe, low voltage power supply
    • communication by (virtual) Ethernet link
    • user interface program on MCU
