    The warranties set forth in this section shall be of no force or effect with respect to any Product: (i) that has been altered or subjected to misuse, negligence or accident, or (ii) that has been used in any manner other than in accordance with the instruction provided by Teledyne API or (iii) not properly maintained.
  • Page 11 Photometric Calibrator Instruction Manual, 01124, Rev. J1 NOTE Model 401 Photometric Calibrator is designed to be a dedicated calibrator. The M401 Photometer should not be used as a monitor. The Beer-Lambert equation, shown below, calculates the concentration of ozone from the ratio of light intensities.

  • Page 12: Interferent Rejection

    It should be noted that the UV absorption method for detecting ozone is subject to interference from a number of sources. The Model 401 has been successfully tested for its ability to reject interference from sulfur dioxide, nitrogen dioxide, nitric oxide, water, and meta-xylene.
