ECHO HandO2 portable oxygen analyser for MAP packaging<\/span><\/h2>\n

Optical tips below 140 \u00b5m enable micro-invasive measurement without sample extraction or oxygen consumption. Two sterilizable probes, salinity compensation and battery operation suit both laboratory and mobile checks.<\/p>\n

Key benefits<\/h3>\n
    \n
  • Gas- or liquid-phase measurement<\/li>\n
  • No sample extraction and no O\u2082 consumption<\/li>\n
  • Micro-invasive optical sensors and two sterilizable probes<\/li>\n
  • Fast user calibration<\/li>\n
  • Battery or mains operation; IQ\/OQ available<\/li>\n<\/ul>\n

    Applications<\/h3>\n
      \n
    • Blisters, vials, tubes, patches and sealed bags<\/li>\n
    • Food and beverage MAP packaging<\/li>\n
    • Biotechnology, micro-respirometry and marine research<\/li>\n
    • Process checks and research & development<\/li>\n<\/ul>\n

      Frequently asked questions<\/h3>\n

      Can it measure dissolved oxygen?<\/strong><\/p>\n

      It supports liquid-phase measurement; suitability depends on the sample, probe and procedure.<\/p>\n

      Can users calibrate it in the laboratory?<\/strong><\/p>\n

      Yes. A two-point calibration using nitrogen and synthetic air is specified.<\/p>\n

      Is it suitable for very small volumes?<\/strong><\/p>\n

      Yes. Optical sensors are designed for very small headspaces and micro-invasive measurement.<\/p>\n

      <\/h3>\n

      Send APEL Laser your sample type, applicable method, required capacity and desired parameters. We will recommend the suitable ECHO configuration, accessories and implementation plan.<\/p>\n
