Oxygen Deficiency Monitor Model O2000 This unique and compact oxygen monitoring system from Air Liquide should be installed in any confi ned space where inert gases might accumulate. This includes gas storage areas, freezers, confi ned spaces and other locations where low oxygen levels may pose an asphyxiation hazard. Unlike electrochemical sensor cells, Air Check features an exclusive, current limiting zirconium oxide oxygen sensor that will operate continuously for 10 or more years with little or no maintenance. It responds to low oxygen conditions within seconds, providing drift-free oxygen readings, even in areas where temperature, barometric pressure and humidity levels are variable. With the Air Liquide Air Check monitoring system, there are no zero or span calibration pots to adjust. Exposure to a reference gas is never necessary. Moreover, when compared to disposable-type sensors that are no longer effective after approximately one year of service, Air Check is easily the more cost-effective oxygen monitoring solution. Our Air Check monitor with long-life zirconium O2 sensor pays for itself in as little as three years! Air Check transmits continuous oxygen concentration levels to any system control data acquisition system or programmable logic controller. It can be confi gured as a display-only monitor or a full-featured monitor with dual-level, user-selectable alarm relays that can be operated remotely up to 1,000 meters from centralized controllers. Suitable for both indoor and outdoor applications, Air Check electronics are housed in a Nema 4X housing, with an optional EX available for hazardous areas.

Oxygen Carbon Dioxide Monitor Model O2CO2000 This unique and compact dual monitor from Air Liquide is ideal for the continuous monitoring of both O2 and CO2 gases simultaneously to alert and protect personnel from entering potentially hazardous situations where inert gases may accumulate. This includes nitrogen gas storage areas, CO2 beverage gas distribution areas, confi ned spaces and other locations where low oxygen or elevated carbon dioxide levels may pose a health hazard. Model O2CO2000 Unlike continuously depleting electrochemical sensor cells, the Dual Air Check monitor features exclusive zirconium and patented NDIR cells to provide stable readings. O2 and CO2 readings are stable even in areas where temperature, barometric pressure and humidity levels are continually changing. The O2 sensor requires no quarterly calibration or annual maintenance, while the CO2 sensor automatically adjusts to ambient levels. Dual Air Check automatically adjusts to ambient CO2 levels on a weekly basis, or on-demand if desired. In addition, there are no zero or span adjustments to make or expensive maintenance required. Simply plug Dual Air Check into any standard AC outlet and depend on continual, maintenance and error-free air monitoring. Dual Air Check has individual dedicated user-selectable relays that can be used to operate on-off valves for the control of CO2 injection in grow rooms while simultaneously activating alarms when O2 levels get too low. The O2 sensor can also be used for controlling nitrogen generators for hypobaric rooms while using the CO2 sensor to alarm to TLV levels of CO2. A built-in CPU provides an inexpensive monitor with local display, safety alarms and control for both O2 and CO2 simultaneously.

Intelligent Gas Detector Model GD-70D The Model GD-70D smart gas detection transmitter series from Air Liquide sets a new standard for performance, flexibility and versatility. The GD-70D sample-draw transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings such as our hydrogen-specific or LEL versions. The long life, high-capacity pump and wide variety of sensing elements are replaceable in a few seconds, with no tools required. The smart sensors retain all calibration and sensor-specific data in non-volatile memory, so sensors can be hot-swapped in the field with no programming required. The sensors also retain calibration information, which means they can be conveniently calibrated separate from the transmitter, avoiding transport of calibration gases to field locations. The GD-70D firmware automatically corrects for longterm zero and span drift minimizing maintenance and maximizing reliability. The GD-70D can be used as a stand-alone device, offering a number of communication protocols to existing PLC systems, or can be integrated with the Beacon series of single and multi-channel controllers. Model GD-70 All GD-70D transmitters include a large, easy-to-read integral LCD display, tri-color bar graph for visual notification of alarm status, programmable low and high alarm relays, and fault relay. Pump flow is self-tuning for maintenance-free operation. Because all GD-70D base units are identical, sensors can be interchanged with no programming or tools required, resulting in maximum flexibility to the user. TOOL-FREE MAINTENANCE!

Hydrogen-Specific Sensors/Transmitters Models Direct Connect, S2 and M2A Air Liquide offers unique proprietary sensor technologies for hydrogen-specific detection in either % LEL or ppm ranges. By utilizing a proprietary molecular sieve coating that is built into both our catalytic or solid state sensors, false alarms from typical hydrocarbon-interfering gases are essentially eliminated. For the LEL range, a special catalytic sensor is coated with a molecular sieve that eliminates the response to common background gases like IPA, methane, gasoline, etc., while providing a detection range of 0 100% LEL for hydrogen. The hydrogen ppm sensor can reliably detect leaks 20 times smaller than a standard catalytic sensor. This solid state sensor has a molecular sieve coating on the sensing element, which filters out interference from other gases and provides 0 1000 ppm or 0 2000 ppm range. Both the LEL and ppm range sensors are available with S2 transmitters with linear 4-20mA outputs. The LEL range sensor is also available with M2A Series smart transmitter, as well as with our Direct Connect sensor used exclusively with Beacon 110 and 410 controllers.
