Manufacturer recommended: Industrial-grade workplace breathalysers should be calibrated every 12 months.
NOTE:
Due to continuous product development and advancements in sensor stability and calibration technology, our devices now sustain their accuracy for extended periods.
Consequently, a single annual calibration is sufficient to ensure optimal performance and full compliance with our NATA standards.
