  The phase shift dphi is the fundamental unit measured by the optoelectronics in the PyroScience read-out device (see chapter 8.3). Please note, that dphi is not at all linearly dependent on the oxygen units, and increasing oxygen levels correspond to decreasing dphi values, and vice versa! As a thumb of rule, anoxic conditions will give about dphi = 53, whereby ambient air will give about dphi = 20.

The REDFLASH technology impresses by its high precision, high reliability, low power consumption, low cross-sensitivity, and fast response times. The red-light excitation significantly reduces interferences caused by autofluorescence and reduces stress in biological systems. The REDFLASH indicators show much higher luminescence brightness than competing products working with blue light excitation. Therefore, the duration of the red flash for a single oxygen measurement could be decreased from typically 100 ms to now typically 10 ms, significantly decreasing the light dose exposed to the measuring setup. Further, due to the excellent luminescence brightness of the REDFLASH indicator, the actual sensor matrix can be now prepared much thinner, leading to fast response times of the PyroScience oxygen sensors.
