Window Energy Profiler (WP4500) Check Availability

This window energy profiler measures the transmittance of ultraviolet, visible, and near infrared light through windows. The instrument also estimates the solar heat gain coefficient values for transparent Low E and clear windows. It is not intended for use with tinted, colored, or reflected (mirrored) surfaces, including window film products. The wide instrument opening allows measurement of windows with the sash or frame already attached.
