PureAire 99188 Sample Draw Dual Oxygen 0-25% and Carbon Dioxide 0-50,000 ppm Monitor

The Sample Draw Dual O2/CO2 Monitor is a self-contained system that is designed for continuous monitoring of inert gases in confined spaces. The monitor can sample O2/CO2 levels from up to 100 feet away and is ideal for facilities that use inert gases, including, but not limited to, nitrogen, helium, and argon. The NEMA 4X/IP66 dust and water-tight enclosure will protect the monitor against dust, water, and damage from external ice formation. The O2/CO2 monitor is perfect for wet or humid environments that do not require daily washdowns, such as agricultural grow facilities, breweries, bottling plants, food processing facilities, and laboratories. The monitor will remain accurate at temperatures as low as -40C. PureAire's durable, zirconium oxide sensor cells, and NDIR cells, will last up to 10+ years in a normal environment, without needing to be replaced.

Features:

• No calibration is required for oxygen
• Self-calibrating CO2 sensor
• Two local backlit concentration displays - one for oxygen, one for carbon dioxide
• Two 4-20mA output signals with dedicated circuits
• Two alarm level set-points for both O2 and CO2
• Two relays for both O2 and CO2
• No drift due to environmental or temperature changes
• No scheduled maintenance zirconium oxide O2 cell and long-life CO2 sensor
• Built-in flow sample pump for remote sampling up to 100 feet
• NEMA 4X/IP66 Enclosure
• Includes 24V 48W Power supply

Long-Lasting Sensors

The PureAire Sampe Draw Dual O2/CO2 Monitor is a compact gas monitoring system ideal for continuous monitoring of both oxygen and carbon dioxide gases. It is intended for use in nitrogen gas areas, CO2 food and beverage areas, confined spaces, and other locations where low oxygen levels and high levels of carbon dioxide may pose a hazard to personnel.

PureAire's Dual O2/CO2 is made with a proprietary zirconium cell and patented NDIR cell, rather than a continuously depleting electrochemical sensor cell. The zirconium cell means the monitor can provide stable oxygen and carbon dioxide readings despite changes in temperature, barometric pressure, and humidity levels.

The PureAire oxygen sensor requires no quarterly calibration or annual maintenance, and the CO2 sensor automatically adjusts to ambient levels. All you need to do is connect the monitor to a power source and let it run in the background-no scheduled maintenance is required!
