Continuous Particulate Matter Monitor (FEM PM Monitor)

Continuous Particulate Matter Monitor measures and records airborne particulate concentration levels using the industry-proven principle of beta-ray attenuation (US EPA Federal Equivalent Method). The data collected is accurate and reliable. The monitoring and data management are operated by the microcomputer system, which can inspect continuously.

The system is equipped with a temperature control system to make the particulate matter monitoring module operate in an environment consistent with standard air monitoring, ensuring its stability and high accuracy.

Real-Time Particulate Matter Air Sensor

Real-Time Particulate Matter Air Sensor is an online monitoring product used to provide real-time and accurate detection data of outdoor ambient air pollutants. This air sensor is capable of meeting the purpose of the continuous monitoring including 24-hour average Respirable Suspended Particulates (RSP) concentration, 24-hour average Fine Suspended Particulate (FSP) concentration and 1-hour average RSP concentration. It adopts a pumping sampling method and can be equipped with a variety of high-precision air sensors according to actual conditions. The monitor is capable of detecting PM2.5 (FSP), PM10 (RSP) and meteorological parameters including temperature, humidity, pressure, wind speed, wind direction with high precision and high accuracy.

Capable in outdoor environment and continuous monitoring such as construction site air quality real-time monitoring or EM&A projects in Hong Kong to ensure that any deteriorating air quality can be readily detected and timely action can be undertaken.

Unmanned Vessel System for Water Quality Monitoring

Unmanned vessel system mainly comprises of an electric unmanned vessel, a water sampling unit, a water quality monitoring unit and a base station computer. The vessel has a built-in Global Positioning System (GPS) and an automatic water quality monitoring system. The vessel will perform water sampling and real-time water quality monitoring according to the preset monitoring point.

To cope with local monitoring requirements, our unmanned vessel can provide water sampling and monitoring at different water levels at the same points. The huge vessel size allows large amount of water sampling at one trip.

The system would automatically generate water quality analysis after the completion of the monitoring mission in the online platform. Uumanned vessel system can reduce the safety risk of life and enhance work efficiency.
