NABL Accredited Air Quality Meter Calibration Services in Pune: Technical Precision

Comprehensive Service Offerings

To ensure air quality data remains accurate and audit-defensible, we apply rigorous calibration methodologies tailored to the sensing principles & environmental challenges of air quality measurement.

• Sensor Cross-Sensitivity Evaluation: Many gas sensors respond not only to their target gas but also to interfering compounds commonly present in region's chemical and textile environments. During calibration, our technicians expose sensors to controlled reference gases to quantify cross-sensitivity effects and apply precise correction factors, preventing false alarms or under-reporting in real operating conditions.

• Zero and Span Drift Verification:
  Over extended use, electrochemical, PID, and NDIR sensors can experience baseline (zero) drift and span degradation due to aging, dust loading, and prolonged chemical exposure. By performing zero-air validation and multi-point span checks, we identify sensor drift early and restore measurement accuracy, ensuring reliable long-term monitoring and regulatory compliance.

• Response Time and Stabilization Analysis:
  In high-dust and high-humidity industrial settings, air quality sensors may exhibit delayed response or signal instability. We conduct controlled response-time testing and stabilization verification to confirm that meters reach equilibrium within acceptable limits, ensuring timely detection of hazardous conditions during safety-critical operations.

Specialized Methodologies for Technical Integrity

Expert Service Offerings: NABL & ISO/IEC 17025:2017 Compliant

At Vega, we treat Air Quality Meter calibration as a high-precision metrological science rather than a routine functional check. We move beyond basic verification by performing a full characterization of the instrument’s performance across its entire measurement range. This process accounts for critical factors such as sensor cross-sensitivity, baseline drift, and the gradual degradation of electrochemical and optical sensing elements—issues that can introduce serious errors if left unmonitored. Our laboratory employs ultra-stable gas-blending systems and laser-referenced particulate generators, creating a controlled, high-resolution environment essential for precise air quality validation.

We perform precision calibration for CO₂ , Carbon Monoxide (CO), and Volatile Organic Compounds (VOCs) using NIST-traceable reference gases to determine linearity and sensitivity. We test the meter’s internal temperature and humidity sensors, ensuring air quality readings are correctly compensated for the region's diverse climatic cycles. Every calibration results in a comprehensive certificate featuring a detailed Uncertainty of Measurement (MU) budget, essential for satisfying MPCB and global automotive/IT auditors.
