Dual O2 & CO2 Monitor & Analyzer

No maintenance zirconium O2 cell and long life CO2 sensorNo calibration required for oxygenSelf-calibrating CO2 sensorLocal backlit concentration displayBuilt-in audible hornBuilt-in visual LED alarm indicatorsAlarm level 1 and 2 for O2 and CO2No drift due to environmental or temperature changes3 year warrantyFeaturesThe PureAire Dual O2/CO2 Monitor is a compact gas monitoring system that's ideal for the continuous monitoring of both gases simultaneously in N2 gas storage areas, CO2 beverage gas distribution areas, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel. Unlike continuously depleting electrochemical sensor cells, the PureAire Dual O2/CO2 exclusive zirconium cell and patented NDIR cell provide stable oxygen and CO2 readings even in areas where temperature, barometric pressure and humidity levels are changing. The PureAire Dual O2/CO2 oxygen sensor requires no quarterly calibration or annual maintenance and the CO2 sensor automatically adjusts to ambient levels. Just plug it in and leave it alone.AdvantagesNo calibration requiredThe Dual O2/CO2 Monitor does not require quarterly calibration. The earth is a wonderful source of calibrated oxygen, and under ambient levels, PureAire's Combo monitor is continuously being challenged to 20.9%. Additionally the ambient earth levels of CO2 are 400ppm. Every week, or on demand, the monitor automatically adjusts to ambient CO2 levels. There are no zero or span adjustments to make or expensive maintenance required.Plug & Play OperationThe Dual O2/CO2 Monitor is ready to go right out of the box. Just mount it to wall or other surface and plug in the power supply into any wall socket. After a 4-minute start-up sequence, the monitor automatically starts operating.Dual O2/CO2 monitor installationsThe Dual Monitor is used in restaurants where CO2 and nitrogen are used to dispense beverages and agricultural grow rooms to alert and protect personnel from entering potentially hazardous situations if a leak occurs.Dual O2/CO2 monitor Control FeaturesThe Dual O2/CO2 Monitor has individual dedicated user selectable relays designed to operate on-off valves for the control of CO2 injection in grow rooms while simultaneously activating alarms when oxygen levels get too low.SpecificationsSampling Method & RangeDiffusion, 0-25% O2, 0-10,000ppm CO2Accuracy± 1% of full scaleOperating Temperature-0 to + 55 CDisplay¾" backlit LCD digital displaySensor TypeLong life zirconium oxide sensor for O2 and NDIR for CO2Alarm indicatorsBuilt-in Audible 90dB hornOrange LED alarm indicator for CO2 Red LED alarm indicator for O2Signal OutputsOne user adjustable Alarm relay for Oxygen One user adjustable Alarm relay for CO2 Relays are rated 2 amp 24VDC / 24VACAnalog OutputAnalog 4-20mA output.
