Adapter Fitting
Low flow - dual modes
The LFS is an ultra low flow sampler
designed for air sampling on the SIS
Thermal Desorption Sample Tubes.
Constant flow mode sampling
Ideal for single or "in-series" tube sam-
pling providing constant flow rates from 5cc
to 200 cc/min. The flow is adjusted through
the sampler with an adjust flow screw.
The pump will automatically maintain
the flow set over the constant flow range at
back pressures up to 25" H
2
O.
External flow adjust
Externally adjustable flow control valve,
settable over the full range of the flow.
Flow fault indication LED
A latching fault function is standard on
all LFS-113 samplers. An LED fault indica-
tor will light if the unit is operated outside its
performance range. If the fault is not cor-
rected within approximately 30 seconds, the
pump will shut off and the LED will remain
lit. The time will lock and display the time at
which the fault occurred, ensuring a valid
sample. If the fault condition is cleared, the
LED will extinguish and the unit will contin-
ue to operate normally.
Battery check LED
When the unit is turned on, an LED indi-
cator signals to show that the battery will
provide a minimum of eight hours service
over the operating range.
Rechargeable battery pack
The LFS has a rechargeable battery
pack system which makes it completely
portable. Battery packs are recharged via a
standard 120V charger.
Dual filtration system
The dual filtration system provides an
internal pump filter providing a needed
backup to prevent destructive gas and
moisture vapors from entering and damag-
ing the sampler. The inlet filter is easily
unscrewed and filters replaced for preven-
tive maintenance protection.
Intrinsic safety
UL approval for use in hazardous loca-
tions Class I Groups A,B, C, D, Class II
Groups E, F, G, and Class III for explosive
gas and dust atmospheres.
Warranty
The LFS sampler is guaranteed for one
year against defects in parts and/or work-
manship.
Elapsed time clock
A time elapsed clock provides for accu-
rate timing and valid sampling data. If the
unit should fault, the clock will latch the time
and indicate on the display. When the fault
is cleared the sampler may be re-started
and the clock will begin a new timing
sequence.
RFI shielding case
This sampler is provided with an EMI-
RFI shielded case to dissipate electromag-
netic and radio frequency interference, pro-
tecting the pump electronics and ensuring
valid sampling data. Pumps have been
designed to dissipate EMI between 13.5
MHz and 495 MHz at the exposure level set
by ANSI C95. 1-1982.
