The OMEGA® miniature, low-cost, high-performance infrared sensor/ transmitter model OS136 features a 19 mm (3⁄4") OD by 89 mm (3.5") long stainless steel NEMA 4 (IP66) housing. This mini transmitter is ideal for applications that require measuring temperature in hard- to-reach, confined, or harsh environments. The OS136 comes with a 1.8 m (6') shielded cable for power and output connections. Models feature industry standard
outputs that provide easy interfacing directly to all meters, controllers, data loggers, recorders, computer boards, and PLCs. The fixed emissivity of 0.95 allows for quick and easy measurement requiring no adjustment during installation
and use.
