The Met One E-Sampler is a rugged, highly-portable and easy-to-use real-time particulate monitor which uses near-forward light scattering, a method as accurate as standard filter methods. Ambient temperature and pressure are measured, and actual flow is calculated and controlled by a microprocessor, independent of filter loading change.

Filters in the E-Sampler can be extracted and replaced in less than one minute, and the filter medium can be selected based on laboratory analysis. Particulate loading on the filter does not reduce performance due to Met One technologies.

Turning the monitor on will initiate sampling using the most recent parameters. The unit will continue to operate until user intervention or battery failure. Auto-Zero and Auto-Span ensure that the data collected will be of the highest quality. Both Zero and Span can be operated manually or individually programmed at varying time bases (15 minutes to 24 hours). The E-Sampler can also be configured for start/stop times, recording periods, averaging time and other parameters.

Data is collected onto an internal logger and can be downloaded to a PC using the manufacturer’s software. PM10, TSP, PM2.5, or PM1 can be measured when using the correct inlet adaptor.
