CLKT IR Window for Outdoor and Indoor Applications 4 5 1 1
This product was very easy to install. This product came with easy to follow installation instructions. We installed them on almost every piece of equipment in our plant in just a short amount of time. Some equipment could not be shot with an infrared camera in the past due to limited shutdown time. In just a couple of weeks our infrared survey capabilities were right on track. August 14, 2012

With a Kwik Twist cover that magnetically sticks to the panel when removed, Fluke IR Windows are easy to use and deliver unmatched image clarity through a CLIRVU® crystal. Exclusive to Fluke IR Windows, CLIRVU crystal technology is impervious to both moisture and vibration. CLIRVU crystals are designed to withstand the extreme pressures and temperatures of an arc-fault event, and offer protection from molten projectiles associated with arc-flashes.

  • Engineered and tested to withstand electric-arcs up to 50 kA for30 cycles.
  • Certified by UL & CSA for Type 3/12 (Outdoor) environments in North America, these C-Range windows are tested to withstand the long term aging effects of UV exposure.
  • Certified by SIRA Certification IP65 (Outdoor) environments in Europe.
  • The CLIRVU® coating—exclusive to Fluke IR Windows—seals the optic prior to assembly to protect against moisture degradation.
  • Own a Fluke Camera? The Quadraband™ optic is IR-Fusion® compatible, allowing the thermographer to see potential problems in visual light and thermographic mode.
  • Got more than one window per panel? Each C-Range window is delivered with an identification plate attached for unique, on-site numbering for rapid location confirmation and faster repairs.
  • Each infrared window comes complete with a security access key, installation instructions and self-adhesive drilling template.
