CFK1 – OpTIONAL ChEMICAL FILTEr KIT (NOX FILTEr)
CO sensors may respond to gases other than CO, resulting in slightly elevated readings. On low NOx
equipment this impact will be very small, often less than the tolerance of your meter. If you anticipate high
levels of SO2 or NOx, UEi recommends using our CFK1, in-line chemical filter. The CFK1 will remove NOx and
SO2 from the gas sample, allowing a true view of the CO only. The CFK1 is compatible with most portable CO
and Flue Gas Analyzers, installs on the sample line before the instrument, and need for replacement is easy
to determine.
AMBIENT AIr MEASurEMENTS
When testing for CO in rooms, make sure the meter has been switched on in outdoor fresh air before the
meter is calibrated.
After the countdown is finished and the meter is correctly set up, take the meter into the room to be tested,
make sure its pump is on and use the probe to draw in ambient air for the meter to measure.
• Only switch on the meter in OUTDOOR, FRESH AIR
• Do not exceed the meter’s internal temperature operating range
• Do not put the meter on a hot surface
• Do not expose yourself and others to dangerous levels of CO
prINTINg TEST INFOrMATION
An optional accessory for the CO95 is an infrared thermal printer. Read the manual supplied with the printer
prior to operation. Connection to the CO95 is detailed below.
• Infrared thermal printer - this does not require
a cable to transmit the data but uses an infrared
(IR) link similar to a TV remote control. The
IR emitter is positioned on the top of the CO95
and the bottom of the printer. Ensure they are
pointing at each other and within 3 feet (1 meter),
with no obstructions in the way. Data may be
lost if transmission is interrupted. Keep the CO95
pointing at the printer until the printout has
finished.
During tests the CO95 will print data on request. With the
analyzer showing the “MAIN dISpLAy” press
“
“ and current data will be sent to the printer.
The display will show “prINTINg” until data transmission
is complete.
