KWIK DRAW UNIPHOS
Airtester HP
(Multiport Sampling)
for compressed air according to EN 12021
Instruction for use
1. Use
The compressed air monitoring set “KWIK DRAW
UNIPHOS Airtester HP” (HP = high pressure) is used
to determine the content of carbon monoxide, carbon
dioxide, oil and water vapour in respirable air from
compressors and compressed gas cylinders.
.
According to EN Standard 12021 air for respiratory
equipment must meet the following quality
requirements:
CO content max. 15 ppm
CO content max. 500 ppm
2
Free of odor and taste, i.e. practically free of
critical mineral oil content (from experience the oil
content is less than 0.5 mg/m³)
Water content in compressed air cylinders:
max. 50 mg/m³ at a charging pressure of 200 bar
max. 35 mg/m³ at a charging pressure of 300 bar
max. 25 mg/m³ of the air from the compressor
-
-
-
-
The requirements concerning the maximum water
vapour content refer to the type of equipment used
(200 or 300 bar) and, therefore, apply also to each
pressure level of the compressed gas cylinders
below the maximum values given above.
.
All maximum values are based on air not under
pressure.

Measuring ranges of the Detector Tubes:
Carbon monoxide detector tubes
5 to 70 ppm carbon monoxide at a flow rate of
0.3 l/min in a measuring time of 5 minutes. (required
sampling volume 1.5 l).
See also specific instructions for use of the KWIK
DRAW / MSA AUER detector tubes CO-HP.
Carbon dioxide detector tubes
100 to 2000 ppm carbon dioxide at a flow rate of
0.3 l/min in a measuring time of 5 minutes. (required
sampling volume 1.5 l).
See also specific instructions for use of the
KWIK DRAW / MSA AUER detector tubes CO2-HP.
Oil detector tubes
This type of tube indicates semi-quantitatively mineral
and synthetic Oils.
Check for oil contents (vapor + mist) at a flow rate of
2.5 l/min in a measuring time of 24 minutes. (required
sampling volume 60 l). The content of oil is determined
as per the instruction given to use the KWIK

6. Maintenance
6.1 General
In view of the significance of the accuracy of
measuring results, the test device must be treated
with care. Dirt must be avoided at all time, especially
at the high-pressure connection.
Flushing and cleaning of the test device must be
made as described in para. 5.2. After measuring is
completed, the test device shell is stored in the case.
The high pressure connection should be closed with
a protective cap.
Function checks should be made at regular intervals
and if erroneous measurements are suspected.
6.2 Disorders
If the hand wheel of the test device cannot be
loosened while it is connected to a compressed gas
cylinder or compressor, check if connection is under
pressure. In this case close the cylinder valve or
compressor valve and release air from test device.
Leaks at the connection to the cylinder or
compressor could be due to a defect gasket. In this
case replace the gasket.
If the high pressure gauge or the detector tube holder
is defective, they must be replaced.
In case of other disorders the device should be
returned for repair to UNIPHOS or any authorized
service station.

The pressure in the compressed gas cylinders, or
in the compressor charging panel is reduced by a
pressure reducer. The air to be sampled is taken
continuously via a regulatory valve in the manifold.
There are four outlets for this manifold which release
fixed flow rate of gas. The flow rate of each port is
printed on the body of the manifold, viz 0.3 l/min,
0.3 l/min 1.0 l/min and 2.5 l/min. The air coming out
from these ports is taken through detector tube for a
specific time. The length of stain in the detector tube
is an index of the concentration of the measured
substance. This can be read directly from the detector
tube scale.
The test device, consisting of pressure reducer,
Pressure gauge, manifold, flow meter, detector
tube holder, adapter for connection to a
compressor charging panel ( for charging
connection 300 or 200 bar), timer, detector tube
tip breaker, tubes (package of 10) for measuring
CO, CO2, water vapor and oil content (sum of
Oil vapor and mist). .
