Barnes Engineering 11-120 Temperature Controller This is a used item. It is in good cosmetic condition. It is also labeled, "Infrared Systems Model 11-120". The dial turns the analog temperature display which is a slide or belt mechanism. This unit powers on and the meter reads, "Above Set Point". With the switch off, the meter reads, "Set Point". The power cord is not in good condition on the back of the case as can be seen in the last picture. We are not able to test it further. It is missing two rubber feet from the bottom. It has a circular 7 pin female connector on the back. It does not come with any cables or accessories. It only comes with what is shown in the pictures. WF K2-8 d 8228198 rl fdk 80717218 81029218
