1.0 INTRODUCTION

The LFS-113 series sampler provides a rugged, reliable and compact sampling
system for industrial hygiene and environmental sampling employment of single or
multiple sorbent tubes and gas sampling bags. Two low flow modes of sampling
allowconstant flows from 5-200 cc/min., as well as constant pressure for multiple
sorbent tube sampling from 1-350 cc/min. (combined flow rates). A compact and
lightweight sampler, the LFS combines convenience and useful functions for accurate
sampling.

1.1 Theory of Operation

The LFS low flow sampler offers two modes of sampling which are easily activated
by turning the selector dial located at the back of the sampler. A hex wrench is inserted
and turned to the desired position and a visual indicator displays the mode being used.
The sampler is turned on and will run continuously until manually shut down. An
optional LCD clock is available on DC models which offers elapsed run time and an
instant-fault function.The constant pressure (multi-flow) mode when used with a
multiple flow controller tube holder, offers a multi-tube sampling capability that is
adjusted individually at each tube position.

1.2 General Description (see figures 2 and 3)

Item Nomenclature Description
1 Charging Jack Receptacle provides means of connecting charger for recharging

internal battery pack.

2 Pump Filter 10 Micron Nylon filter protects pump assembly from dirt. Discolora-

tion indicates need for filter replacement.

3 Mode Indicator Visually confirms mode engagement via Black or White indication.
4 Mode Select Provides means of unlocking, indexing and re-locking mode selector

valve to change from constant low flow to the multiple low flow mode.

5 On/Off Switch Activates sampler operation.
6 Battery Check Green LED indicates sufficient battery power to run the pump for an 8-

hour period under normal load conditions.

7 Fault Indicator Indicates flow fault due to excessive pressure or insufficient battery

voltage to maintain flow.

8 Clock Display Indicates continuous run-time in minutes which will lock in the sample

(DC models only.) time upon fault indication. Time will reset to zero when the power

switch is turned OFF and back ON.

9 Flow Adjust Provides external means of adjusting the air flow rate.
10 Inlet Boss Air inlet is located on the clear filter housing and provides built-in

means of attaching tubing for suction sampling.

11 Outlet Port Receptacle for discharge air boss accessory. The cap screw prevents

dirt from entering the dischargeoutlet when not in use.

12 Discharge Boss An accessory which when installed into the discharge outlet, provides a

means of filling air sampling bags.

13 Belt Clip Built-in means of attaching sampler to worker’s belt.

14 Case Screws (4) Holds battery pack in place as well as case front and back.

15 Battery Pack Provides DC power to operate the unit.
