Textile Sweating Guarded Hotplate

Main Feature and Function:

1, Small repeatability error: The core part of the instrument – heating control system is a special device developed independently, which theoretically eliminates the instability of the test results caused by thermal inertia, and the invention of this technology has been approved, so that the error of repeatability testing is much smaller than the relevant standards at home and abroad, the current “heat transfer performance” class of testing instruments are mostly repeatability error in ± 5%, the company has reached ± 2%, can be said to solve the problem of long-term repeatability error of insulation class instruments, reached the level.
2, Compact structure, strong integrity: Thermal and humidity resistance tester is a host and small climate box into a whole device, without any external device can be used independently, adapt to the environment is stronger, to reduce the use of conditions specially developed a thermal and humidity resistance instrument.
3, Real-time display of “heat and humidity resistance” values: After the specimen is preheated to the end of the whole “heat, moisture resistance” value of the stabilization process in real time, so as to solve the problem of doing heat, moisture resistance experiments for a long time and can not understand the whole process.
4, Highly simulated skin sweating effect: The instrument has a high simulation of human skin (hidden) sweating effect, different from only a few small holes in the test board, to meet the test board everywhere water vapor pressure equal, the effective test area is accurate, so that the measured “wet resistance” is closer to the true value.
5, Multi-point independent calibration: Due to the large range of heat and humidity resistance test, multi-point independent calibration can effectively improve the error caused by non-linearity, to ensure the accuracy of the test.
6, Microclimate temperature and humidity consistent with standard control points: Compared with similar instruments, taking the microclimate temperature and humidity consistent with the standard control point is more in line with the “method standard”, while the control requirements of the microclimate is higher.
