A New Standard in Real-Time
Aerosol Monitoring
The E-SAMPLER is a comprehensive system
that provides both real-time monitoring and filter-based sampling capability. Whatever
your monitoring objectives, the E-SAMPLER will provide accurate, dependable and relevant
data.

Technology
The E-SAMPLER combines real-time
measurement utilizing light-scatter technology, and the ability to conduct gravimetric and
chemical analysis.
Particulate loading on the filter does not reduce the performance of
the light-scattering detector. Flow, temperature and pressure parameters are continuously
measured, allowing the on-board microprocessor to control the actual sampling rate. |

Principle
The E-SAMPLER provides real-time
measurement through its near-forward light scattering technique. The on-board sample pump
draws air at 1.0 to 3.5 lpm into the sensing chamber. A state-of-the-art detector measures
the intensity of scattered light, which is proportional to the particulate concentration. |
Maintenance
In addition to the 47mm sample filter,
the E-SAMPLER has two internal filters. One protects optical surfaces and the other
prevents damage to the flow controller. Both filters are easily accessible from the front
panel. Filter life will exceed one year of operation in the harshest of conditions. |

|
A curtain of clean air continuously protects all optical
surfaces within the detector. This sheath-air allows the instrument to be used in adverse
environments without performance degradation.
Operation
The E-SAMPLE is
rugged, portable and easy to use. Initial set-up is simple. Once configured, simply
turning the monitor on will begin operation. The unit will continue to operate until user
intervention, or the battery has failed.
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 programmed to occur at user specified intervals.
The E-SAMPLER
can also be programmed to operate at defined intervals (start / stop times). Other
parameters that may be controlled by the user include recording periods and averaging
time.
