    产 地：德 国  （*）

       TIR100–2热发射率测定仪，应用范围广泛,可在数秒钟内快速确测定物体表面热发射率，实为测量发射率进行有效质量控制的理想设备。
 

TIR 100-2可在数秒钟内测量物体表面的热发射率。即使是特殊结构和曲面也可以直接测量，该设备自成一体，包含全部操作和电子元件，可测量和处理传感器信号和显示数据，以及控制黑体温度。                             
TIR 100-2是*的TIR 100的更新设备，我们不但在TIR 100-2中融入了TIR 100的可靠技术，还高度集成了电子元件和舒适的触摸屏使设备更加轻巧和易于使用。
内部微控制器可将发射器温度调节至恒定的100℃，同时记录传感器信号并配合存储的标准值将其转换为发射率的值。
大屏幕LED显示设备的状态，测量结果和操作菜单，触摸屏面板确保所有功能轻松实现。
设备的核心部件是半球形的黑体，由于发射器涂有黑色涂层，因此具备近乎理想黑体的所有属性。发射器的工作温度为100℃，黑体外壳的其余部分与发射器热绝缘。因此在仪器运行过程中仅产生轻微热量。
仪器内部的逆向热熔丝防止发射器加热时产生过多热量，并可在125℃中断加热过程。
热电堆传感器将反射的热辐射转换为电压信号，并按照特定温度下的普朗克黑体定律给出热辐射的光谱分布图。超过97%的辐射能的波长在2.5 μm和40 μm范围之间。

应用：
1.镀膜玻璃的质量控制
  热保护绝缘玻璃的的低U-值取决于玻璃镀膜的低发射率，TIR 100对镀膜的质量控制以及实验室中开发新镀膜非常有用。
 2.太阳能收集器生产的质量控制
  优质的太阳能收集器的效率取决于收集器表面非产低的发射率，因此TIR 100也是此行业质量控制的理想设备

TIR100 - 2
Determination of thermal emissivities within seconds
NEW !
The TIR 100-2 measures thermal emissivities of surfaces within some few seconds. The measurement can be performed directly at the original part and even structured and curved surfaces can be measured. The instrument contains all operating elements and electronic components for the measuring and processing of the sensor signals and their display, as well as for the control of the black-body temperature.
The TIR100-2 is the follow up device of the known TIR100 for measuring thermal emissivities of surfaces. We combined the reliable technology of the TIR100 with highly integrated electronics and a comfortable touch screen. The stand - alone instrument is now more compact and easier to use.Inside a microcontroller regulates the temperature of the radiator to a constant value of T = 100°C. At the same time the signal of the sensor is registrated and converted by the help of the stored standard values into an absolute value of emissivity. The large LED illuminated display shows instrument status, measuring results and operational menues. The touch screen panel guarantees easy operation of all functions. The essential part of the instrument is the half sphere shaped black body. Due to its black coating the radiator has all the properties of a nearly ideal 'black body'. The radiator works at 100°C. The
remaining part of the black body housing has been thermally insulated against the radiator. There is a slight heating of the device during operation. The heating of the radiator is protected against overheating with a reversible thermo-fuse, which will interrupt the heating at a temperature of 125°C. The thermopile sensor changes the reflected thermal radiation into a voltage signal. The spectral distribution of the thermal radiation is given by Planck's law of a black body at given temperature. More than 97 % of the
radiation energy is ranging in the wave length region between 2.5 μm and 40 μm.
