1.107-GF
The 1.107-GF is our standard configuration which reduces filter maintenance
to only once a year. However, it utilizes a depth filter which gives up
to one year of uninterrupted operation. The
bottle is also used to collect any possible moisture
accumulation during standby periods.
1.107-PTFE
If single flat dust composition filter analysis is required, the Model
1.107
can also be equipped with an optional integrated filter
holder for use with our 47mm hydrophobic PTFE filters which allow a
post-analysis of the collected dust. Our automatic flow control system
maintains a constant the sample flow performance of the GRIMM monitor.
Maintenance
Each 1.107 spectrometer undergoes two factory calibrations. First with monodisperse latex spheres of known diameter at multiple points.
Second, a polydisperse NBS approved dust mixture to assure proper mass
conversion of the 31 different size channels. Only an annual
recalibration is recommended in accordance with ISO 9001.
To verify the instrument performance, all GRIMM equipment report not
only the measurement data, but also the instrument performance and/or
possible errors. These data are available via RS-232 but are stored on
the data logger as well. They can be downloaded via telephone or internet
from the client.
Our annual inspection package with calibration is part of our worldwide
dealer network commitment. Each Model 1.107 and 1.165 has internal filters to
protect sensitive optics and to assure particle free rinse air. These
filters as well as some O-rings should be changed annually.
