How often does the Q-Trak IAQ Meter require factory calibration?

The Q-Trak IAQ Meter requires factory calibration annually to ensure accurate measurement of indoor air quality parameters. Regular calibration is essential for maintaining the precision and reliability of the instrument's readings. Over time, sensors can drift and become less accurate due to environmental factors and wear. By calibrating the device once a year, users can ensure that the data collected is trustworthy and that any potential issues with sensor performance are addressed in a timely manner. This is critical for occupational hygiene, where accurate monitoring of air quality can impact health and safety in the workplace.
