The two-stage calibration process for Oizom's devices sets us apart in ensuring the accuracy of our air quality monitors. First, meticulous lab calibration takes place using known concentrations of gases traceable to NIST standards. This eliminates inherent sensor errors and establishes a baseline for precise measurement.

Following this controlled environment calibration, our devices go a step further with co-location calibration. Here, the monitors are placed in real-world conditions alongside highly accurate reference-grade monitors that meet US EPA standards. By comparing the Oizom unit's readings to these trusted sources, Oizom accounts for any environmental influences that may affect sensor response. This two-pronged approach guarantees that Oizom monitors deliver the most accurate air quality data possible.

Oizom has a custom-built reference station with USEPA-designated FEM reference grade analyzers. The reference station has the capacity to accommodate up to 40 Oizom units simultaneously, enabling further assessment of intra-model variability using statistical measures like mean, median, and standard deviation. But Oizom understands that long-term accuracy is crucial.

Our monitors are designed for on-site calibration using various methods to address this. This empowers users to maintain the precision of their monitors throughout their lifespan. Oizom offers the flexibility of performing on-site calibration using standard calibration gas cylinders or by co-locating with a reference standard.
