Series 500 Portable Air Quality Monitor

The Series 500 air quality sensor enables accurate real-time surveying of common outdoor air pollutants, all in an ultra portable handheld monitor. Air quality professionals typically use the Series 500 for short term air quality studies and carrying out checks on pollution “hot spots”. The Series 500 can also be deployed for short term fixed monitoring by adding an optional outdoor enclosure.

Data is stored on board the Series 500 with a maximum 8,188 records available. To download the data a USB cable is supplied for connection to PC. Free PC software provided with the Series 500 takes the data and presents it in a chart or table view. Data can be downloaded and viewed in Excel.

Like all our handheld monitors the Series 500 portable air quality sensor takes advantage of the unique sensor head format. Sensors are housed within an interchangeable cartridge (“head”) that attaches to the monitor base. The head can be removed and replaced in seconds, allowing users to measure as many gases as they wish. Sensor heads feature active fan sampling which ensures a representative sample is taken and therefore increases measurement accuracy.

Other features on the Series 500 include monitor ID and location ID. Monitor ID identifies the monitor uniquely and ensures that all data from it are tied to that monitor. Location ID can be used to tag measurements to a specific location which is helpful when sampling at a number of sites over the course of a day or week.

The Series 500 is also featured in our new Outdoor Air Quality Test Kits, a convenient way to test multiple gases and particulates in the air around you.
