| DUAL TECHNOLOGY |
The E-SAMPLER is a dual technology
instrument that combines the unequalled realtime measurement of light
scatter with the accuracy standard of filter methods. The simple filter
loading process testifies to the seamless blending of both technologies.
Filters can be extracted and replaced in less than one minute and
filter medium can be selected based on laboratory analysis. Particulate
loading on the filter does not reduce performance due to the Met One
actual flow control protocol. Ambient temperature and pressure are
measured and actual flow is calculated and controlled by the E-SAMPLER
microprocessor independent of filter loading change. |
| PRINCIPLE |
The E-SAMPLER provides
real-time particulate measurement through near-forward light scattering.
An internal rotary vane pump draws air at 1 to 3.5 LPM into the sensing
chamber where it passes through visible laser light. Aerosols in the
air scatter light in proportion to the particulate load in the air.
Scattered light is collected by precise glass optics and focused on
a PIN diode. Rugged state of the art electronics measure the intensity
of the focused light and output a signal to the CPU. The output is
linear to concentrations greater than 100,000 ug/m3. Every
E-SAMPLER is factory calibrated using Polystyrene Latex Spheres of
known index of refraction and diameter at multiple points to validate
linearity. |
| MAINTENANCE |
Each E-SAMPLER has two internal filters (not the 47mm Analysis Filter) to protect sensitive optics and prevent damage to the flow components. Both filters are accessible from the front panel. Coin slots enable these filters to be removed and checked or replaced without any tools. Filter life for both will exceed 1 year in the harshest of conditions. All E-SAMPLERs have sheath air from the internal filters that continually curtain the optics. This sheath air protection allows the E-SAMPLER to be used in adverse environments without performance degradation. Even in harsh conditions the E-SAMPLER will operate to specifications for 2 years without need of recalibration. |
| OPERATION |
The Esampler is rugged,
portable and easy to use. The all aluminum enclosure is not only rugged
but provides electronic stability by filtering potential RF interference.
Setup is a snap with the quick connect ratchet system which works
with many different pipe sizes. For other mounting applications, holes
are provided to fasten to any structure. Simply turning the monitor
on will start a sample 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 COLLECTION AND SOFTWARE |
Air SoftwareTM and
Air Plus SoftwareTM are complete communications, data collection and
data reporting tools. This software supports modem, radio, direct
connection and the G1002 Data transfer module. Both programs generate
summary reports and Air Plus provides graphic recordings and charts. |
