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.
