Ultrasonic Oxygen Indicator
INTRODUCTION
Thank you for purchasing a PRO
2
check
®
Ultrasonic Oxygen Indicator. The
designers of this product have years of experience in the field of oxygen
concentrator repairs. The unreliability and high cost of operation of fuel
cell analyzers led to the invention of the
PRO
2
check
®
Ultrasonic Oxygen
Indicator.
By relying on a method already used in many oxygen concentrators to
trigger "Low O
2
" alarms – ultrasound – Salter Labs has produced a more
cost effective product to check the output of oxygen concentrators. The
PRO
2
check
®
Ultrasonic Oxygen Indicator responds faster, has no fuel
cell
to replace and is simpler to use than a fuel cell analyzer.
Directions for Use:
There are two (2) controls for the
PRO
2
check
®
unit:
1. Pressing and releasing the “on/off” button will turn the unit on or off.
2.
The “pure O
2
calibrate” button when pressed and held down
while connected to a compressed gas or liquid U.S.P. oxygen
(>
99.0%) source verifies that the unit is properly calibrated, thus
eliminating the need to have an outside source calibrate the unit.
Since the PRO
2
check
®
device uses ultrasound technology to check the con-
centrator operation, there has to be two modes of operation:
1. When the unit is turned on, the software enables the unit to
measure the output of an oxygen concentrator adjusting for the
argon that passes through the sieve beds.
2.
When using the unit with the “pure O
2
calibrate” button
depressed the software measures oxygen not adjusting for the
argon. When the “O
2
calibrate” button is released, the unit
automatically returns to the concentrator mode and will then again
adjust for the argon and read incorrectly for pure oxygen.
We are sure that the PRO
2
check
®
Ultrasonic Oxygen Indicator will
provide years of fast, reliable operation.
