  • Provides typical 18 hour battery life


Fluke CLKT Infrared Windows are Available in Three Sizes 50 mm (2 in), 75 mm (3 in) and 100 mm (4 in)

Each CLKT infrared window is engineered and tested to withstand electric-arcs up to 50 kA for 30 cycles.

The ClirVu® coating - exclusive to Fluke infrared windows - seals the optic prior to assembly to protect against moisture degradation making it perfect for very hot and very cold outdoor environments.

Each Fluke infrared window is delivered with an identification plate attached for unique, on-site numbering for rapid location confirmation and faster repairs.

CLKT infrared windows come complete with a security access key, installation instructions and self-adhesive drilling template.

For 5 minute or less installation and Autoground consider the CV300.


World’s smallest, lightest and most portable dry-wells
  • Smallest dry-wells in the world
  • Ranges from –10°C to 122°C
  • Accuracy to ±0.25°C, stability of ±0.05°C
  • RS-232 interface
  • Fluke Calibration’s line of portable dry-wells is incredible. They’re the smallest, lightest, and most portable dry-wells in the world. And now they're better than ever!


  • Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected
