Polludrone ensures accuracy through different stages of calibration, which are discussed below:

Factory and Field Calibration

Accuracy begins right at the source. Every Polludrone goes through a detailed, multi-stage calibration process. The Polludrone sensor is individually calibrated in a controlled laboratory environment using certified gas standards. This lab calibration ensures that every sensor measuring gases delivers accurate and consistent readings from the moment it’s deployed. After lab calibration, it is further collocated with reference-grade analyzers in a controlled setup. Every Oizom device is calibrated at our dedicated calibration facility, established at ATIRA, Ahmedabad. Each calibration report is then verified by ATIRA, ensuring you receive data that’s not just accurate but also trusted and validated by experts.

Why does Polludrone truly stand out in the air quality monitoring market?

Because we don’t just build monitors; we build trust in data. Every Oizom air quality monitoring device is first calibrated in an ISO/IEC 17025:2017 certified lab using NIST-traceable gas standards, strictly following international guidelines (U.S. EPA Vol II, Section 6.0 Rev.1).

But we don’t stop there.

After lab calibration, each device goes through a second level of testing, collocation with a custom-built reference station equipped with U.S. EPA-designated Federal Equivalent Method (FEM) analyzers. This double-layered approach ensures that Polludrone delivers data you can depend on every single time.

At Oizom, we take data accuracy seriously. Our Polludrone Smart has undergone rigorous field evaluations, including benchmarking by third-party validation programs like AQ-SPEC (Air Quality Sensor Performance Evaluation Center) by South Coast AQMD.

e-Breathing Technology

One of the most unique features of Polludrone is its patented e-breathing technology, a dynamic air sampling method that mimics how humans inhale air. Unlike traditional static sensors, e-breathing creates an airflow cycle within the sensor chamber, pulling in ambient air at regular intervals. This active sampling mechanism reduces the chances of sensor drift and improves data consistency, especially in fluctuating outdoor environments. The result? More representative and reliable readings, even in locations with variable wind flow or temperature changes.

Data Quality and QA/QC

Maintaining reliable data doesn’t stop at calibration. Polludrone is equipped with internal diagnostics that continuously monitor sensor health, power levels, and communication performance. In case of sensor errors or power issues, the system generates real-time alerts, helping you take immediate action. Features like auto-cleaning mechanisms, data smoothing algorithms, and redundant data backups on internal memory further enhance the device’s QA/QC (Quality Assurance/Quality Control) capabilities.
