  • Page 9: Introduction

    Introduction Introduction Teledyne Analytical Instruments MX300-I Oxygen Monitor with alarms here after referred to as MX300-I is a portable instrument that provides fast and accurate oxygen monitoring and incorporates an audio/visual alarm capability. These instruments are designed to monitor up to 100% oxygen concentration in medical gas mixtures. Because they are microprocessor-based, the MX300-I instruments have a unique combination of features that make them very easy to use.

  • Page 10: Applicable Standards

    The alarm circuitry provides both an audible and visual alarm. 1.1 Applicable Standards The MX300-I units are built to meet or exceed regulatory and industry standards for use as a medical device. The instruments are designed, built and tested with the following applicable standards:...

  • Page 13: Sensor

    1.5.1 Sensor The MX300-I uses the Teledyne Class R17MED disposable oxygen sensor. The sensor is made up of a sensing cathode and anode (fuel) immersed in electrolyte and packaged in a small plastic container.
  • Page 14 The oxygen level is calculated and then displayed on the liquid crystal display (LCD) on the front panel. In the MX300-I monitor, user-programmed high and low alarm set points are stored in random access memory (RAM), which resides within the microprocessor. The oxygen level calculated by the microprocessor is compared to these set points, and an alarm activated, if necessary.
