DescriptionExtraordinarily efficient in design, the OS36-APC needs water flow rate of only 0.05 gpm (190 cc/min.) to protect an infrared thermocouple at 540°C (1000°F). This convenient and inexpensive kit makes it possible to use either the OS36 or OS36-2 with air, water or both for service in harsh environments. Measuring only 25 x 100 mm (4" x 1") overall, the OS36-APC is small enough to fit into tight areas to closely monitor process temperatures up close (in the optimum position). It can withstand the harshest environments with its all stainless steel housing.
