Gas Analyzers #4991740

The O2Cap family integrates an Oxigraf oxygen sensor with a NDIR CO2 sensor for dual gas measurements for research, industrial and laboratory measurements. Measure Oxygen concentrations from 5-100% and CO2 from 0-10%. Perform capnography tests with fast breath by breath measurement. The units come with a pump for gas sampling system, bright vacuum fluorescent alphanumeric display (VFD), touch panel keypad, a rear 0-1VDC analog output for O2 readings, and either a rear terminal strip with limit detection relays and 4 20 mA analog outputs or a second CO2 analog output, and a RS232 digital interface.

The model O2Cap and O2CapB have luer type front panel gas sample input fitting for research applications. The model O2CapD have CPC O-Ring quick connect gas sample fittings for industrial applications.

All of the Model O2Cap, O2CapB and O2CapD include a sampling pump that will draw a sample from atmospheric pressure; with an external flow control valve, it will accommodate pressurized gas up to 1.3 psig (17 psia or 120 kPa).

An optional gas sampling valve allows the pump to draw a sample for a programmable number of seconds. This feature is useful for sampling from Modified Air Packaging (MAP). Please contact Oxigraf for more information on this option.

O2Cap comes with LEUR fitting and gas sampling pump. PN 07-0193

O2CapB replaces the Terminal Strip with a second BNC analog output for CO2 on the regular O2Cap. PN 07-0387

O2CapD come with CPC O-ring fitting and gas sampling pump. PN 07-0358

The Model O2T and O2TR are oxygen analyzers for medical oxygen trans-filling and verification and designed for measuring 5-100% oxygen in nitrogen. These units are easy to use and feature bright LED displays, touch panel controls, easy calibration, a sample pump or regulator for flow control depending on model, and CPC front panel fittings. The Model O2T has a built-in sampling pump with flow from 0-250mlminute. The Model O2TR has a built in regulator for flow control and features a simplified two (2) point calibration control on the front panel. Comes with a carrying case and optional printer and rechargeable DC battery pack for portable use.

An On-Board Inert Gas Generation (OBIGG) system is now mandatory for many civilian and military aircraft to prevent the buildup of explosive conditions in fuel tanks by generating Nitrogen Enriched Air (NEA) to lower the oxygen content in the fuel tank headspace or ullage. Oxigraf provides a complete system for validating the performance of your OBIGG system.

The Oxigraf O2N2 oxygen analyzer characterizes the performance of an OBIGG system over an entire flight profile from takeoff, climb, cruise, and descent by measuring the oxygen concentration at multiple sites in the fuel tanks every 16 seconds.

The O2N2 analyzer is a specialized instrument evolved from Oxigraf oxygen analyzers commonly used for medical, scientific, and industrial process and safety applications. The patented laser diode absorption spectroscopy technology employed by Oxigraf is a natural fit for analyzing oxygen concentrations in a Jet-A fuel-air mixture as only light comes in contact with the gas sample, and the gas sample is maintained at a low temperature. The sensor responds in milliseconds, has no cross sensitivity to other gases, corrects automatically for changes in temperature and pressure, measures quickly over a wide dynamic range, and is insensitive to vibration.

The aircraft OBIGG validation system is comprised of several rack mount Oxigraf O2N2 oxygen analyzers mounted in a rugged rack system along with manual cut-off valves, regulators, purge and calibration gas supplies, and a laptop computer with the OxiFTE system control and data logging software. Fuel tank sample kits with float valves and tubing to sample locations complete an installation.

Additionally, the system has features to mitigate risks of escape of the sample gas, such as monitored nitrogen purging of the electronics enclosure. The OBIGG test system also features float valves at the fuel sample point to prevent ingestion of fuel at the sample location. Manual shut-off valves and test ports a low total system validation and operator intervention if necessary to remove the analyzers from contact with the fuel system.

The number of O2N2 analyzers in a system depends on the number of sample points required in the fuel tank system to be monitored, with each O2N2 analyzer having four (4) sample channels. The example system shown below is comprised of twelve (12) channels mounted in an 18U chassis with the other parts of the system. Oxigraf can provide standard 12U and 18U chassis along with custom racks as required for the application.

Here is a truly digital oxygen analyzer with analog and digital interfaces for control, display, and data logging of either nitrogen blanketing of powder storage or of nitrogen content in recirculation pneumatic transport systems.
