Detectieapparatuur voor warmteoverdracht voor verwarmingsradiatoren is ontwikkeld door het Instituut voor Bouwfysica, de Chinese Academie voor Bouwwetenschappen, volgens de huidige nationale norm GB/T 13754-2008. Wordt gebruikt voor het detecteren van de warmteafvoer per tijdseenheid van een verwarmingsradiator en de thermische sterkte van metaal. Deze apparatuur is geschikt voor het verwarmen van radiatoren met warm water als verwarmingsmedium.

9.Product features
1）The unique thermal medium circulation system ensures the stability of radiator inlet pressure and the accuracy of temperature.
2）All heating water tanks are double-layer thermal insulation structure and lined with stainless steel plate, which means the thermal insulation has good anti-rust performance.
3）The whole piping system adopts seamless stainless steel pipe, which has high resistance to high temperature and high pressure, and good rust resistance.
4）PT1000 temperature sensor is adopted as the temperature measuring element, with basic error less than ±0.1℃, high accuracy and good stability.
5）The measurement and control software is adopted by senior testers with Windows 95/98/2k /XP platform and VB/VC hybrid programming to control the whole detection process with a convenient and flexible human-machine dialogue interface. The report and original record are processed by Microsoft Word, and users can modify and make their own format. The report format of the national construction engineering quality supervision and inspection center is attached to the software for users' reference.
6） The advanced data collection and processing system can automatically analyze and process the test results, and issue the test report and original records.
7）Open Accessa database management, with strong compatibility, can be seamlessly connected with any management software interface.
8）The equipment has automatic protection functions of overcurrent, overpressure, phase and break, and runs stably and reliably.
