The Series 500 enables accurate real-time surveying of common indoor air pollutants, all in an ultra-portable handheld indoor air quality monitor.  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.
The monitor can also operate in control mode. Upper and lower control limits can be easily set directly on the display. Using the 0-5V output the Series 500 can be used to switch on or off an externally connected device, such as an ozone generator, or system in the presence of a predetermined level of gas. By selecting the optional wall-mount bracket and plugging in mains power the Series 500 is effectively able to act as a fixed monitor as well as a handheld portable device.
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.
