ALUSYS is a measuring system for trend-monitoring and mobile survey of heat flux and surface temperature in industrial environments. Sensors and electronics have the robustness necessary for this application. Powered from a low-voltage rechargeable battery, it is easy and safe to use. In its standard configuration the system consists of an MCU Measurement Control Unit in a metal housing and 12 x heat flux and surface temperature sensors of model HF01. Measured data are stored for later analysis. -
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

TRSYS01 is a high-accuracy system for on-site measurement of thermal resistance, R, thermal conductance, the Λ-value, and thermal transmittance, the U-value, of building envelopes. TRSYS01 is mostly used for measurements according to standard practices of ISO 9869 and ASTM C1155 / C1046. The system is equipped with high-accuracy electronics, two heat flux sensors of model HFP01 as well as two pairs of matched thermocouples. The two measurement locations provide redundancy, leading to a high level of confidence in the measurement result. The high accuracy of the heat flux sensors and temperature difference measurements ensures that TRSYS01 continues measuring when other systems no longer perform; in particular at very low-temperature differences across the wall.- Temperature difference sensors: tested for 0.1 °C accuracy requirements
- Superior heat flux sensor, stable: waterproof (IP67), corrosion-proof
- Continues measuring when others give up: high sensitivity amplifier + high sensitivity sensors
