The OMEGA miniature, low-cost, high-performance infrared sensor/ transmitter model OS136A features a 19 mm OD by 89 mm long stainless steel IP66 housing. This mini transmitter is ideal for applications that require measuring temperature in hard-to-reach, confined, or harsh environments. The OS136A comes with a 1.8 m screened 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.
