Scope

Main technical content: 3. Overview The on-site testing equipment for the thermal performance of building envelopes is used to detect the insulation and heat transfer performance of the envelopes. 4. Measurement characteristics 4.1 Temperature: Control range (-60 to 100)°C, maximum allowable error ±0.5°C. 4.2 Heat flow: Control range (0.3 to 200) mV, maximum allowable error ±0.1 mV. 5. Calibration conditions 5.1 Environmental requirements 5.1.1 Environmental temperature: (20 ± 5)°C; Relative humidity: (40 to 80)%; 5.1.2 The surrounding environment should be free from heat or cold sources, vibration, electromagnetic interference, pollution, and corrosive gases that may affect the calibration.
