Description
The Palas AQ Guard is currently the most advanced portable aerosol monitor of its type in the world for real-time indoor / outdoor particle and air quality measurements. This unit is a state-of-the-art, research grade, high resolution spectrometer capable of providing highly accurate measurements. The Palas AQ Guard features a wide 175nm to 20um particle size range, 64 high-resolution particle size channels, a massive 10 GB of data storage, and many other features WAY beyond the capabilities of competitive instruments on the market.
A newly developed mass conversion algorithm calculates PM values based on single-particle optical light scattering, taking signal duration and shape into account. The sensor system and advanced algorithms were developed based on the same technology as used in the MCERTS & EN 16450 certified Palas Fidas 200 series. An outdoor-rated ambient version of this model is also available (with heated aerosol inlet) which achieves precision comparable to type approved compliance grade instruments.

Web Interface
The Palas AQ Guard features fast data interfaces and allows real-time access over Ethernet, WiFi, or a cellular network. Since all the results are calculated and recorded within the analyzer it requires no external data processing. Users retain full control over their data and decide over information access. The AQ Guard can also provide numerical data, using various communication protocols, as well as visualize information on any type of device using a modern web interface.
