Professional IAQ Sensor Calibration Services in Singapore
Precision. Reliability. Confidence.
Your indoor air quality sensors are only as good as their last calibration. Over time, environmental exposure, sensor ageing, and contaminant buildup cause readings to drift — quietly undermining the accuracy your facility depends on.
Axiom Laboratories provides professional calibration services for all three GoodAir sensor models — IQ1, IQ2, and IQ5. We help Singapore facilities maintain measurement accuracy, support compliance awareness, and extend long-term confidence in their IAQ monitoring investment.
Why Calibrate with Axiom Laboratories
Maintain Measurement Accuracy
Sensor accuracy naturally deteriorates over time. Routine calibration addresses environmental fluctuations, sensor ageing, and gradual degradation from contaminants — keeping your readings trustworthy and your decisions informed.
Support Compliance Awareness
Calibration helps facilities demonstrate due diligence in indoor air quality management. Regular recalibration creates a documented record of sensor performance that supports quality programmes and facility audits.
Extend Sensor Lifespan
Well-maintained sensors last longer. Periodic calibration identifies performance drift early, allowing corrective action before small inaccuracies become major problems. Protect your investment. Maximise your return.
Physical Calibration, Not Data Corrections
Some sensors claim automatic background calibration. These are data corrections, not physical calibration. Without a known reference standard, long-term accuracy cannot be guaranteed. Axiom Laboratories performs physical calibration with traceable reference equipment.
Quarterly or Annual Scheduling
Axiom Laboratories offers flexible calibration intervals to match your operational needs. Choose quarterly verification for high-demand environments or annual calibration for standard deployments.
Covers All GoodAir Models
Axiom Laboratories professionally calibrates the complete GoodAir sensor range: IQ1, IQ2, and IQ5. One partner. One process. Complete peace of mind.
Why Calibration Matters
Indoor air quality sensors operate in challenging environments. Temperature swings. Humidity changes. Dust, vapours, and airborne contaminants. Over months of continuous operation, these factors cause sensor response to shift — often so gradually that the drift goes unnoticed.
Without regular calibration, your facility could be making decisions based on inaccurate data. Ventilation adjustments timed wrong. Comfort complaints unexplained. Compliance gaps invisible until they become problems.
According to SS 554:2026 Annex I, the accuracy of low-cost IAQ sensors can deteriorate over time, making regular inspections and recalibrations necessary to ensure continued effectiveness.
Singapore IAQ Standard Reference
The standard recommends quarterly verification using calibrated reference sensors or annual calibration with manufacturers or accredited facilities.
Axiom Laboratories follows these established guidelines to deliver calibration services that keep your GoodAir sensors performing at their best — quarter after quarter, year after year.
Reference: SS 554:2026 Annex I — Low-cost IAQ sensors, Section I.5 Calibration. GoodAir calibration services support alignment with this guidance. Project-specific compliance requirements should be reviewed with qualified consultants.

Every facility that relies on IAQ data benefits from regular calibration.
Hospitals & Healthcare
Patient safety depends on data you can trust.
Healthcare facilities cannot afford inaccurate environmental readings. Quarterly calibration ensures your GoodAir sensors continue delivering precise data that supports patient comfort, hygiene management, and care environment monitoring.
Airports & Transport Hubs
Passenger spaces need sensors that perform under pressure.
High-traffic terminals experience constant environmental change. Regular calibration keeps your IQ2 sensors accurate across departure halls, gate lounges, and transit corridors.
Government Buildings
Public accountability starts with reliable data.
Government facilities need documented sensor performance to support facility reporting and indoor environmental quality programmes. Annual calibration provides the records and confidence public-sector management demands.
Commercial Buildings
Tenant confidence is built on accurate readings.
Office towers, shopping malls, and mixed-use developments rely on IAQ data for HVAC optimisation and tenant satisfaction. Calibrated sensors mean better decisions and fewer complaints.
Schools & Universities
Fresh-air data helps students perform at their best.
Classroom CO₂ levels directly affect student alertness. Annual calibration ensures your IQ5 sensors continue providing accurate readings that help facilities teams manage ventilation.
Hawker Centres & Food Courts
Busy dining spaces need sensors that keep up.
High-occupancy food spaces with cooking activity and variable ventilation place unique demands on sensors. Regular calibration ensures reliable data in these challenging environments.

Frequently Asked Questions
SS 554:2026 Annex I recommends quarterly verification with calibrated sensors or annual calibration with manufacturers or accredited facilities. Axiom Laboratories offers both schedules. High-occupancy environments like hospitals and airports benefit from quarterly service. Standard deployments typically need annual calibration.
