Oxygen Detector, Controller and Transducer for Fire Detection Panel

The OX-6 from MACURCO is a detector, low voltage controller and transducer, that integrates double relay, 4-20 mA selectable output: buzzer and digital screen, is an electronic sensing system used to measure Oxygen (O2) concentration and provide feedback and control of the automatic ventilator/exhaust fan to maintain the appropriate oxygen concentration in commercial applications. The OX-6 is a low level meter capable of recording 0 to 20% oxygen level.
