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 continue 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.
