Dual O2/CO2 Monitor

This duel sensor monitor is designed for use in areas containing Helium, Argon, and/or Nitrogen, that contain CO2 as well. It includes all of the top of the line features of our air check oxygen deficiency monitor, though it monitors the level of CO2 in the room as well. It is ideal for use in environments such as breweries, beverage or other bottling plants, pharmaceutical manufacturing facilities, or grow rooms. This monitor contains a 10+ year zirconium oxide sensor. Features: The 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 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. No maintenance zirconium O2 cell and long life CO2 sensor No calibration required for oxygen Self-calibrating CO2 sensor Local backlit concentration display Built-in audible horn Built-in visual LED alarm indicators Alarm level 1 and 2 for O2 and CO2 No drift due to environmental or temperature changes 3 year warranty Specifications: ampling Method & Range Diffusion, 0-25% O2, 0-10,000ppm CO2 Accuracy � 1% of full scale Operating Temperature -0 to + 55 C Display �� backlit LCD digital display Sensor Type Long life zirconium oxide sensor for O2 and NDIR for CO2 Alarm indicators Built-in Audible 90dB horn, Orange LED alarm indicator for CO2, Red LED alarm indicator for O2 Signal Outputs One user adjustable Alarm relay for Oxygen, One user adjustable Alarm relay for CO2.
