1概述
WP4500窗玻璃能量检测仪可用于工厂测试玻璃，也能测试已经安装好的窗玻璃。只要打开窗户在玻璃的外框处移动WP4500执行能量测量。仪器的开口加大能够插入大部份窗玻璃的框架。
WP4500测量紫外线（UV（A）），可见光（VLT）及近红外线（NEAR IR）等窗玻璃或贴膜的传输数据。此仪器也能够测量Low-E及透明窗玻璃的太阳能源幅射率（SHGC）。此仪器的SHGC测量并不预设使用於著色，彩色或反射性（镜面）表面的玻璃。是一个独立装置，没有另外增加的光源或电力线圈且不需调整。简单的将此仪器在窗玻璃的外框附近移动并且观看显示於仪器上的数据。
2应用
2.1 窗玻璃补修市场。
WP4500可以作为销售工具让业主了解现有窗玻璃性能的不足且需要更换。您能测试顾客的现有的窗玻璃然后用同一臺仪器显示您销售的节能窗玻璃产品的优秀表现。对於窗玻璃贴膜的应用，您能非常快且容易的证明使用前和使用后窗玻璃的测试结果。
2.2在生产检验上，您能确实验证窗玻璃的性能达到正确的标準。
WP4500可以被用於区分不同种类的Low-E镀膜。通过比较从WP4500的测量结果与Low-E镀膜玻璃特性表，您能大致辨认用於窗口的Low-E的种类。当遇到客户抱怨或指责即使收到正确窗玻璃时是相当有帮助的。在工厂，於窗玻璃组装製程中重覆检验确定使用正确的Low-E玻璃。在辨认错误标註或根本没标记的窗玻璃时WP4500是非常有用的。

Common Applications:
• Replacement window sales: The Window Energy Profiler is great for testing the existing windows in a home to determine the necessity for new replacement windows. Comparing existing window performance to the performance of the replacement windows offers quantifiable evidence that the replacement windows will make a difference on energy bills, UV damage, natural daylight, etc. Use it alongside the Window Profiler Sales Guide - a brochure designed to help you use the Window Energy Profiler to you sell your window's energy performance.
• Portable quality control: Test windows at the job site before installation. Snuff out any incorrect windows before they are installed to prevent major time and money consuming headaches.
• Energy Auditors in the field: The WP4500 is the perfect tool to test the energy performance characteristics of installed windows
• Identify and differentiate low-E coatings: By comparing the performance numbers of windows to data sheets, you can determine the type of Low E coating on windows. For example, you can differentiate Cardinal 366 from 272 or PPG SolarBan 70 from SolarBan 60 in production or in the field.

Other Features:
• Automatic calibration: Measurements automatically revert back to '100%' for transmission measurements and '1.00' for SHGC.
• Hold button: By pushing the hold button, the WP4500 will keep your current measurement displayed. This is helpful when you are reaching to take a measurement and the displays aren't visible at the time of the measurement. Also, in the sales process, this feature allows you to keep measurements displayed long enough to explain to your customers exactly what the numbers mean.
• Automatic power-down: This adds to the energy efficiency of the unit and keeps the number of battery changes to a minimum.
• Uses common 9-volt battery: These are simple to find, purchase and replace. You don't have to worry about tracking down an obscure battery or power source at an inopportune time.
• Completely portable with convenient handle for taking measurements: Being battery powered makes this unit completely portable. You can take measurements anywhere.
• Convenient carrying case included: The padded carrying case protects your investment.
*Note: SHGC measurement is not valid on window film or colored glass
