• AE1601 | ETEKT+ Low-E Detector

ETEKT + Low-E Detector

The ETEKT + has been serving an important role for glaziers worldwide for nearly 25 years: locate invisible Low-E coatings on IG units with a definitive, non-destructive test. With the release of the AE1601 (second generation ETEKT+), we've made some improvements to the reliability and temperature stability of the meter without compromising the features our customers have grown to love.

The NEW ETEKT + Low-E Coating Detector allows you to:

  • Confirm the invisible Low-E coating is properly installed on your double pane IG units with a single test from a single side. You can also test a triple pane window by testing both sides of the window. For full triple pane Low-E detection, see the Glass-Chek PRO & Glass-Chek ELITE.

  • During IG fabrication, ensure proper orientation of the Low-E coated glass so it is not damaged by the brushes of the glass washer.

  • Prove to the customer that the invisible, money saving Low-E coating is present on their windows before installation.


Features and Details:

  • Being handheld in size and powered by a common 9-volt battery (included), the ETEKT + is completely portable.

  • Compatible with 3/32" through 1/4" SINGLE pane of glass.

  • Also compatible with 3/32" & 1/8" IG assemblies with 1/4" - 9/16" air space from a single side.

  • Thicker IGs, as well as larger air spaces, can be tested in single pane mode.

  • Compatible with Pilkington OptiView

Upgraded from the original AE1600 Low-E Coating Detector:

  • New: Low Battery Indicator. The Low-E detector will indicate that the battery needs replaced by blinking the LED indicators.

  • New: The AE1601 is much more capable of maintaining accurate results across a wider range of temperatures due to a new temperature stability program incorporated into the design.

The ETEKT + Low-E Coating detector is the industry standard for instruments detecting the presence and location of thermal resistant coatings (Low-E) used on energy efficient single, dual and triple pane glass and window assemblies. The ETEKT+ is a rugged handheld device that is accurate, easy to use, and rarely requires calibration. Place the unit flat on the glass surface, press the button and read the results.
