Product Details:

For Testing Windows In-Frame
Displays Four Real-Time Measurements of Windows: The Estimated SHGC Value Along With the UV, Visible Light, and Infrared Transmission Values
Completely Portable With Convenient Handle for Taking Measurements
Convenient Carrying Case Included

The CRL Window Energy Profiler allows you to test actual windows that have already had the sash or frame attached to the window. The instrument can test windows in the factory, but more importantly it can test windows in the field that have already been installed. Simply open the window and slide the WP4500 around the profile of the window to conduct your performance measurement. The opening of the instrument is actually large enough to fit around the entire frame of many replacement windows before they are installed. The WP4500 measures the UV(A) (ultraviolet), Visible Light (VLT), and Near Infrared (NEAR IR) transmission values for a given window or window film. The instrument also estimates the Solar Heat Gain Coefficient (SHGC) values for transparent Low E and clear windows. The SHGC calibration of this instrument is NOT intended for use with tinted, colored or reflective (mirrored) surfaces, including window film products. Being a self-contained system, there are no additional light sources or power cords necessary and no adjustments to make. Simply slide the instrument around the profile of the window and watch the resulting performance data appear on the display.

Applications Include:

For the replacement window market, the WP4500 can be used as a sales tool to evaluate the poor performance of a homeowner's existing windows showing the need for replacement windows. You can test the customer's existing windows an then use the same instrument to show the excellent performance of the energy efficient window product you are selling.

For window film applications, you can conduct very quick and easy before-and-after demonstrations by adding a piece of film to the window to show the results.

For job-site inspections in the field, you can confirm the performance of windows when they arrive at the jobsite to ensure the correct product was received.

In the field, the WP4500 can be used to differentiate different types of Low E coatings. By comparing the measurement results from the WP4500 to the performance data sheet figures of various Low E coatings, you can roughly identify the type of Low E used in the window. This is a great aid for those troublesome customer complaints that are challenging whether they received the correct windows.

In the factory, double-check windows in the production environment to make sure the correct Low E was used in assembling the window. The WP4500 can be very helpful in identifying windows that are mislabeled or not marked at all.
