1 Introduction
The Certifier
®
Flow Analyzer (FA) Test System allows you to test
respiratory care or other devices. This portable tester makes it simple
to test flows, volumes, pressures, oxygen concentration, and breath
timing. The Certifier
®
FA Test System is designed for institutional,
home care, field service, and laboratory settings.
Certifier
®
FA Test System components include:
Controller module:
The keypad and display allow you to select test measurements
and units for display. The controller module connects to a high or
Low Flow module.
High Flow module:
Measures air or 100% oxygen (O
2
) over a range of flows from 0
to 300 standard liters per minute (SLPM).
Low Flow module:
Measures air, 100% O
2
, or 100% nitrous oxide (N
2
O) over a
range of flows from 0.01 to 15 SLPM with greater accuracy than
the High Flow module at low flow rates.
Oxygen sensor:
Used with the High Flow module, allows the High Flow module to
measure O
2
concentration and other measurements for any
mixture of air and O
2
.
You can connect or disconnect the flow modules and oxygen sensor
at any time during normal operation without interrupting tester
operation. Four AA batteries power the test system. The test system
conserves power by automatically turning off if none of the keys are
pressed for 15 minutes. See
