October 25, 2018
Maxtec has issued a voluntary correction for the Max-550E oxygen sensor which is effective October 25, 2018. When the flow diverter is overtightened, some Max-550E sensors were found to potentially become over-pressured and forced to be unseated from the gas analysis port. This could ultimately cause an inaccurate or slow-response FiO2% reading on the monitor or analyzer that uses this sensor.
