TEST KIT
The test kits includes test gas cylinders, a regulator or dispensing
valve and flowmeter, a test cup, and flexible tubing. The test kit
is housed in a custom storage case.
Test Gas Cylinders
The test gas cylinder for the CO-95 contains 200 ppm of CO in
air. The test gas cylinder for the HS-95 contains 25 ppm of H
2
S
in N
2
. These concentrations are nominal; the actual concentration
is listed on the cylinder label. The cylinder for zeroing the OX-95
contains pure nitrogen (N
2
). The gas is released when the
regulator or dispensing valve is attached to the cylinder and the
flow control knob is opened.
H
2
S Regulator (for HS-95)
The H
2
S regulator allows the test gas to flow to the HS-95 at a
fixed flow rate. The regulator gauge shows the pressure of the gas
in the cylinder. The flow control knob opens and closes the
regulator. To connect, screw the regulator onto the cylinder, and
install the tubing leading to the test cup.
Dispensing Valve (for CO-95 and OX-95)
The dispensing valve controls the flow of test gas to the CO-95 or
the OX-95. The flow control knob opens and closes the valve and
controls the flow rate of the test sample. To connect, screw the
valve on to the test cylinder. Insert the gas outlet into the sample
tubing.
