NOTICE
Immerse the sensor into the calibration as quickly as possible after
opening the ampoule to ensure the best performance and validity of the
calibration liquid.
Do not leave the sensor in the PAH calibration liquid more than 15
seconds since UV light degrades the PAH calibration liquid. After
approximately 15 seconds, the measurement value will be invalid due to
the degradation of the calibration liquid.
