The CRL "Reflex" Coating Detector allows the user to easily identify the coated side of glass for a variety of applications including Low-E, the tin side of clear uncoated float glass, protective and anti-reflective coatings, as well as having the ability to detect and store up to 22 user-programmed coatings.

The RX1550 Coating Detector is comprised of two separate functions: One for identifying coated surfaces, the second for identifying Low-E coated surfaces of the glass. For identifying coated surfaces, the device is a first-surface detector, the meter must be placed against the coated surface it is testing. The Low-E detection function is the only part of this meter that will also check the second surface of the piece of glass you are testing. "Opto-Clean" software technology detects and alerts the user of the build-up of dirt on the lens that could affect reading accuracy.
