Purpose:

The Series 500 portable air quality monitor enables accurate real-time surveys of common outdoor pollutants in a portable device. Compatible with interchangeable sensor heads measuring up to 15 different pollutants (sensor heads sold separately). Suitable for a range of projects including indoor air quality surveys, personal exposure monitoring, and short-term fixed monitoring.

Monitoring data can be transferred to a computer via USB cable for data download and processing.

The Series 500 portable air quality monitor utilizes a unique sensor head format. Sensors are housed in an interchangeable cartridge (head) that connects to the monitor base. Measurement heads can be removed and replaced in seconds, allowing users to measure any number of gases. Sensor heads feature active fan sampling, which ensures representative sampling and improves measurement accuracy.
