PhysFog - A Preview

The Standalone equipment to collect air for the Total Suspended particles(TSP) measurements.

PhysFog is standalone equipment to collect air for the measurement of Total Suspended Particles (TSP) at ambient conditions. It is equipped with a configurable filter head for PM2.5 or PM10. A vacuum pump forces air to run through the filters while keeping a track of the flow rate, humidity, and temperature of the ambient air. Suspended particles are collected on expandable filter papers that are later used for analysis. In addition to the basic characteristics of air listed earlier, PhysFog can also be used with many COTS weather stations on RS485 protocol recording weather variables including wind speed, UV index, and rain count. Not only research but PhysFog can also be deployed to periodically monitor the air quality in critical environments.

The digital controller can be configured using an installation-free web application on any smartphone having working WiFi. The same web application can be used to configure, control and even continuously monitor the system in the WiFi range which can expand up to 200 feet in the open. For a typical session, PhysFog can be configured for maximum run time, sampling period and maximum allowed flow rate using mechanical control valves. Samples of up to 20 days can be stored within the in-built memory chip and viewed interactively any time using the web app.

With a durable mechanical structure, IP54 dust and water ingress protection, tolerance against failed power supply, and a modern user interface PhysFog can serve the need for robust yet affordable dust and weather monitoring station.
