As air pollution and climate-related challenges continue to grow worldwide, universities and research institutions play a critical role in generating reliable environmental data to support scientific research and policy development. The University of Port Harcourt, one of Nigeria’s leading academic institutions, has selected the TH2000A Fixed Air Quality Monitoring System to support its environmental research and long-term air quality assessment projects.

The TH2000A system deployed at the University of Port Harcourt is configured to provide multi-parameter, real-time environmental monitoring, covering air pollutants, particulate matter, meteorological data, and environmental noise. This comprehensive configuration enables researchers to study pollution sources, atmospheric behavior, and environmental trends with high accuracy and continuity.

To meet research-grade requirements, the TH2000A integrates multiple high-performance sensors:

PM2.5

0–1000 µg/m³, 1 µg/m³ resolution

PM10

0–1000 µg/m³, 1 µg/m³ resolution

TSP

0–2000 µg/m³, 1 µg/m³ resolution

CO

0–25 ppm, 0.01 ppm resolution

O₃

0–1000 ppb, 1 ppb resolution

SO₂

0–1000 ppb, 1 ppb resolution

NO₂

0–1000 ppb, 1 ppb resolution

H₂S

0–1000 ppb, 1 ppb resolution

CH₄

0–5000 ppm, 1 ppm resolution

VOCs

0–1000 ppb, 1 ppb resolution

This sensor combination allows researchers to simultaneously analyze particulate pollution, toxic gases, greenhouse gases, and volatile organic compounds, providing a solid data foundation for environmental and public health studies.

In addition to air quality monitoring, the TH2000A system includes a multi-parameter ultrasonic weather sensor (XF600L), enabling synchronized environmental data collection:

Temperature

–40 to +85 °C

Relative Humidity

0–100% RH

Atmospheric Pressure

50–110 kPa

Wind Speed

0–40 m/s

Wind Direction

0–360°

Rainfall (optical principle)

0–200 mm/h, ±5% accuracy, 0.2 mm resolution

A noise meter (30–130 dB) is also integrated, supporting studies on environmental noise pollution in urban and campus environments.

The system is equipped with a DTU module featuring a 4G SIM card slot, ensuring stable real-time data transmission to remote servers. This allows researchers and administrators to access historical and live data remotely, supporting long-term trend analysis, data sharing, and academic collaboration.

By deploying the TH2000A Fixed Air Quality Monitoring System, the University of Port Harcourt has strengthened its capability in:

• Environmental and atmospheric research
• Air pollution source analysis
• Climate and meteorological studies
• Environmental impact assessments
• Student education and field-based learning

The feedback and on-site installation images provided by the university demonstrate the system’s stability, adaptability, and suitability for real-world academic environments, even under challenging climatic conditions.

The successful application of the TH2000A system in Nigeria highlights its flexibility and reliability for universities, research institutes, and environmental agencies worldwide. Designed for continuous operation, high data integrity, and multi-parameter integration, TH2000A is a powerful tool for advancing environmental science and supporting data-driven decision-making.
