1. standard of execution GB/T10294-2008 Thermal insulation Determination of steady state thermal resistance and related properties Guarded hot plate apparatus. 2. Test range 1）Single material: foam (heat insulation material with flat surface, plate), polyurethane, phenolic, ureal, mineral wool (glass wool, rock wool, mineral wool), cement wall. 2)Composite board: glass reinforced composite board CRC, cement polystyrene board, sandwich concrete, fiberglass composite board, paper honeycomb board. 3. Main technical parameters 1)Temperature control precision: hot plate: ±0.1℃ cold plate: ±0.1℃ 2)Maximum setting temperature of hot plate: 95℃3)Cooling: air cooling, water cooling 4)Minimum cold plate temperature of air cooling equipment: -10℃ 5)Minimum cold plate temperature of water cooling equipment: -30℃ 6)Measuring accuracy of the instrument: 3% 7)Thermal conductivity measurement range: 0.010~1.600W/(k·m) 8)Power supply: AC220V 3kW 4. Product features 1)The surface temperature is accurate and uniform. In the design of TPMBE, a large area of whole copper plate is used as the temperature control measuring plate, which makes the surface temperature consistency of the test piece better. 2)Advanced control system. Imported intelligent temperature control instrument with automatic tracking performance, with fast and stable temperature control performance, temperature control precision ±0.1℃. 3)Friendly man-machine interface. Hot plate temperature and cold plate temperature and heat flow power can be read directly from the digital instrument. 4）Simple operation. Electric moving cold plate, clamping force adjustable, specimens installed in place to close the upper left and right insulation door. 5）Intelligent data processing. Highly automated computer data communication and report processing system, plate thermal conductivity with computer communication interface, can be set from the computer hot plate cold plate control temperature, real time display temperature curve. 6）With printed test report. Software built-in test records, data processing and report format, automatically issued reports. 7）Stable and reliable. Safe and reliable automatic protection function, with overcurrent protection function. 5. mode
