PureAire Monitoring Systems is excited to introduce its new Dual Oxygen/Carbon Dioxide Monitor, an important addition to our full line of Oxygen Deficiency Monitors, Carbon Dioxide Monitors, and Combustible/Toxic Gas Detectors.  Our new Monitor is designed for continuous monitoring of oxygen and carbon dioxide levels  across a wide variety of applications, including cryogenic facilities, breweries, food processing plants, cannabis grow rooms, pharmaceutical manufacturing operations, laboratories, hospitals, and universities.
​
Our Dual 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. Its NEMA 4X/IP66 dust-tight and water-tight enclosure will protect the Monitor against dust, water, and damage from ice formation.

PureAire’s new Dual O2/CO2 Monitor continually measures oxygen levels from 0-25%, and carbon dioxide levels from 0-50,000 parts per million (ppm), with both O2 and CO2 measurements readily visible on the Monitor’s easy-to-read backlit displays. Depending on our customers’ specific requirements, the Monitor can be linked to a programmable logic controller (PLC), a multi-channel controller, or tied into building systems themselves.

​The new O2/CO2 Monitor features dual built-in LED visual alarms, two alarm level set-points for both O2 and CO2, as well as two relays for each monitored gas. The Monitor responds in seconds to changes in oxygen and carbon dioxide levels, and it will remain accurate over a wide range of temperature and humidity levels.
​
PureAire’s Dual Oxygen/Carbon Dioxide Monitor offers thorough air monitoring, with no time-consuming maintenance or calibration required. Built with durable, non-depleting, zirconium oxide sensor cells, and non-dispersive, infrared (NDIR) sensor cells to ensure longevity, PureAire’s Dual O2/CO2 Monitor can last, trouble-free, for 10+ years in normal working conditions.

Helium is the second most abundant element in the universe and used across a variety of industries. Valued for more than simply filling party balloons, helium is of critical importance in many commercial applications, including high-tech, automotive, healthcare, and aerospace.

Helium Uses
For instance, the manufacture of fiber optics requires an all-helium environment to prevent air bubbles or other flaws in the delicate fibers used in cables to transmit data. Additionally, the semiconductor industry utilizes the cooling properties of helium to transfer heat away from computer chips during manufacturing.
Helium plays a key role in inflating automobile airbags and may also be used to detect leaks in car air-conditioning systems. Metal fabricators use helium for welding because of its inert properties and high heat transfer capabilities, which make it the perfect shielding gas (an inert or semi-inert gas that protects the weld from oxygen and water) for welding materials with high heat conductivity, such as copper, magnesium alloys, and aluminum.
In the medical field, helium is used to cool the superconducting magnets in MRI (magnetic resonance imaging) and NMR (nuclear magnetic resonance) equipment, to treat medical conditions such as asthma and emphysema, and for laparoscopic surgery.
NASA uses helium as an inert purge gas for hydrogen systems and as a pressurizing agent for ground and flight fluid systems, as well as a cryogenic agent for cooling various materials. Moreover, as in the automotive sector, helium is likewise used in precision welding applications in aerospace manufacturing.

Staying Safe While Working with Helium
Since helium is odorless and colorless, it has no early warning properties. Helium can displace oxygen in the air to levels below what is needed for humans to breathe. Exposure to helium can cause dizziness, nausea, and loss of consciousness. Absent proper oxygen monitoring, unconsciousness, and even death may occur in seconds. The National Institutes for Health recommends installing oxygen monitors anywhere compressed gases, such as helium, are stored or used.

​PureAire Monitors
PureAire Monitoring Systems’ oxygen deficiency monitors continuously track levels of oxygen and will detect helium leaks before the health of employees is put at risk. Built with zirconium oxide sensor cells, to ensure longevity, PureAire’s O2 deficiency monitors can last, trouble-free, for over 10 years under normal operating conditions. In the event of a helium gas leak, and a decrease in oxygen to an unsafe, OSHA action level, the monitor will set off an alarm, replete with horns and flashing lights, alerting staff and users to evacuate the area.
Each PureAire O2 monitor has an easy to read screen, which displays current oxygen levels, for at-a-glance readings by employees, who derive peace of mind from the monitor’s presence and reliability.
