TRSYS20 is a high-accuracy measuring system used in determining the in-situ thermal resistance (R-value), thermal conductance (Λ-value), and thermal transmittance (U-value) of building envelope components. The system is mostly used for measurements according to standard practices of ISO 9869, ASTM C1046 and ASTM C1155. TRSYS20 is equipped with high-resolution electronics, two heat flux sensors of model HFP01 as well as two pairs of matched thermocouples for differential temperature measurements.
