A convenient and inexpensive kit makes it possible to use either the IRt/c or IRt/c.3x with air, water, or both for service in harsh environments. Measuring only 4.16” x 1” (106 x 25 mm) overall, the CJK-1 is physically small enough to fit into tight areas and closely monitor process temperatures from the optimum position - up close. With its all stainless steel housing, it can withstand the harshest environments.

Extraordinarily efficient in design, the CJK requires only .05 gpm (190 cc/min) to protect an IRt/c at 1000°F (540°C). A small amount of air purge insures that optimum cooling is maintained, and prevents condensation on the lens (see Tech Note No. 15).

The water cooling system consists of a seamless monotube, in order to eliminate the possibility of leaking joints. For convenience, the seamless tubing includes an extra 3 ft (1 m) tubing length.
