    MODULAR OXYGEN MONITOR

    1. GENERAL DESCRIPTION

    The Billups-Rothenberg, Inc. (BRI) of Modular Oxygen Monitors (MOM5002) is a range of factory calibrated oxygen sensors which measure ambient pO levels using the principle of electrochemical sensors by oxygen. BRI’s sensors benefit from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle. All O2 sensors are oxygen pressure and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional calibration. Unlike other oxygen sensor technologies, the MOM5002 of oxygen sensing devices, are very stable and do not contain lead or any other hazardous materials.

    1. BENEITS

    The modular oxygen monitor is designed to measure oxygen levels directly from high-pressure cylinders in the range 0.1-100.0% O2. No sampling hoses or accessories are necessary. The modular oxygen monitor is designed as a quick check device to test and verify that previous readings with another analyzer are correct. The modular oxygen monitor uses a digital display with low power consumption, and an Off – On – Calibration knob.Power is provided by a standard alkaline 9-volt battery. The modular oxygen monitor uses an electrochemical O2 sensor to measure O2 content in gases. The sensor is disposable and user-replaceable, with a life expectancy of up to 24 months depending on usage. The sensor and battery are user replaceable. Calibration should always be performed at the same temperature and humidity conditions as the gas being measured. This is not always possible, for example, in a tropical environment where dry breathing gas from a high-pressure Scuba cylinder will be measured after Analyzer calibration has been performed in the warm, humid ambient air. Under these conditions a calibration correction value may be required, as detailed in the Appendix, or dry air must be used for calibration.

     

    4.Operation
    4.1. Open the silicone hole of the monitor for one minute at first. Then, turn the Off/On Calibration knob slowly until a slight hiss can be heard.
    4.2. Turn the Calibration knob of modular oxygen monitor slowly until the reading to stabilize at 20.9% in ambient air.

    4.3 If you cannot obtain a stable reading, check that you still have a very gentle flow of gas and repeat. If you still cannot obtain a stable reading see Troubleshooting section or use another analyzer.

    4.4 Put on the modular oxygen monitor in the hypoxia chamber or another environmental box to check the percent of oxygen.

    4.5 When you finish the experiment, please turn off the monitor and cover the silicone hole at once, to prevent exposure to the air, and prolong it’s lifespan.

    NOTE: There is no need to re-calibrate the unit after analyzing a gas flow. Simply move to the next gas source or allow the reading to stabilize at 20.9% in ambient air.

     

    5.Maintenance
    5.1. During the first 12 months of the warranty period, the modular oxygen monitor should be returned to the dealer/manufacturer for repair. Your modular oxygen monitor should give you one year continuous operation with proper care before needing sensor replacement.
    5.2. To clean the modular oxygen monitor use a damp soft cloth.
    5.3. Although designed to be water-resistant the modular oxygen monitor should not be intentionally immersed in liquid or left outside unprotected.
    5.4. The modular oxygen monitor is built to resist the effects of day to day shocks and drops but remember it is a precision oxygen analyzer and should be looked after carefully to give long trouble free service.
    5.5. Protect the modular oxygen monitor from long periods of direct sunlight and do not subject it to high or low temperature extremes.
    5.6. Battery Replacement – To replace the battery, open the battery case, Replace with new battery and reassemble it. Be careful not to pull too hard, as you can separatethe wires from the end cap and damage the modular oxygen monitor. 

    DO NOT ATTEMPT THIS REPAIR ON YOUR OWN.

    7.Calibration Correction Values for Temperature and Humidity

    Oxygen Analyzer calibration should always be performed at the same temperature and humidity conditions as the gas being measured. Where this is not possible, a calibration correction value may be required. A common example is a tropical environment where dry breathing gas from a high-pressure Scuba cylinder will be measured after Analyzer calibration has been performed in the warm, humid ambient air.

    To determine if a calibration correction value is required, you must first know the temperature and relative humidity of the air in which calibration will be performed. Using the chart below, find the atmospheric oxygen percent value corresponding to your temperature and relative humidity. If the oxygen percent value falls in the
    shaded portion of the chart, calibrate the Analyzer to the corrected chart value.

    If the Temperature and Relative Humidity axis meet in the shaded part of the chart, calibrate to the chart O2 level or with dry air to maintain 0.5% O2 accuracy in NITROX.

    To use the correction value, follow the standard Calibration procedure except as follows:
    Make sure Oxygen Sensor is exposed to the ambient temperature and humidity corresponding to the correction value.
    Adjust the Calibration Adjustment Screw to achieve a Display reading equal to the correction value.
    Once you have calibrated the monitor for temperature and humidity using the, your readings for gas analysis should be correct with no further adjustment.
    Re-calibrate monitor for any changes in temperature or humidity of the ambient environment or the gas being analyzed.
    Note that the calibration correction value is never used when the temperature and humidity conditions of the gas being measured are the same as the conditions during calibration.
